Strange case of changing broadband network address...

Hello - I am new to the forums and would appreciate any advice concerning this enquiry.
We recently got Bt infinity.
All seems well and we have good speed- - we have only been connected for a month.
Recently though a couple of times we have suddenly lost connection, or the connection seems to struggle to connect- this is with the home hub 5.
I am not that technical regarding routers, but my current set up is with the home hub providing our personal network and then we have another router ( lan > Wan) that is used to provide wifi to guests in our adjacent holiday let. This router has dd-wrt installed and is set up to restrict bandwidth to guests. All works well.
However as mentioned recently the connection seems to drop - and also the guest network drops out as well.
I noticed that if I tried a speed test at this time that the IP address had changed to something unrecognisable.
Connecting and reconnecting on the hub usuually solves it - but I don't know why it happens?
Here are the details when everything seems ''normal''
Internet Connection Configuration
Connection Information
Connection time:
0 days, 02:14:43
Data Transmitted/Received:
24.1 MB / 170.3 MB

194.72.0.98
Secondary DNS:
62.6.40.178
And here are the details when thing start to lose connection:

... Is that ''different'' broadband Ip address normal - or not?
If anyone can explain in relatively layman terms - I would be very grateful
Thanks

Solved!
Go to Solution.

Your IP address is dynamically assigned by BT, and will change each time there is a disconnection, or maintenance on the network.

VZaccess Manager changes local network address

I would like to know why VZAccess Manager changes my local network IP address everytime it is installed or there is a program update. My LAN is on 10.0.0.- and VZAccess manager is installed on one computer on the network but every time I've had to re-install or there is a program update it sets the IP address for that computers LAN address to 192.168.-.- and I have to go back in and reset the network address to the proper settings for my network. This is a USB modem acquiring its own address from the Verizon network. Why is it mucking around in my LAN settings? It functions the same on the computer it is installed on no matter what my LAN is on so there is no reason for it to be altering these settings.

I'll give you an explanation of my network configuration and my opinion of the situation and VZ Access Manager and we can go from there.
I have an office in the lower leval of my home with my PC, my laptop and a NAS (an old PIII @1Ghz running FreeNAS to turn it into a Network Attached Storage). PC and NAS and usually the laptop are connected to a switch (their LAnto the switch w/CAT5. The switch is CAT5 to an Ensoniq CB3 for a wireless connection to a Hawkings wireless router w/ a 6.5 db external antenna that is located in the spare room upstairs where the computer my wife uses (on occasion) is also located. The Hawking is connected to the LAN on my wifes computer, connection sharing is set up on that computer too and the Verizon Novatel USB760 is attached to this computer through a USB port. VZ Access Manager is installed on her computer also. I can take control of her computer from downstairs using TeamViewer. The 3 computers and the NAS are on their own workgroup (renamed from 'WORKGROUP' and are also set up using 10.0.0.100, 10.0.0.101, 10.0.0.102 and the NAS is 10.0.0.150.
Everything works perfectly until VZ Access Manager is installed or upgraded at which time it changes the address of my wifes computer (that it's connected to USB to 192.168.1.1, 255.255.255.0, no default gateway or DNS server address which stops my network from working. The USB760/VZ Access Manager have acquired an IP address, mask, gateway and DNS from Verizon and they can be found in VZ Access Manager. It doesn't assign a valid address to the computer it's plugged into.
This is the point where I have to go in and reset that LAN to 10.0.0.100, 255.255.255.0, 10.0.0.10 and I use OpenDNS for all 4 units (and I change VZ Access Manager's DNS to OpenDNS' 208.67.222.222 and 208.67.220.220) and everything works fine until VZ Access manager comes along with another upgrade. My download speeds from any unit run a pretty consistant 680K to 1.3G with everything set as I've explained above.
Now, the USB760 and VZ Access Manager have acquired their address as they should have. There is no reason for the program to go in and alter the settings on that machines LAN because 1) they were already set 2) VZAM is not assigning a working address to that machine anyway, just a generic 192.168 address and wiping the gateway address and the DNS addresses that were in there and not even replacing them and not setting them to 'Acquire an address automatically'.
VZAM and the USB760 would function on this computer even if I pulled the LAN card out altogether so my opinion is that this is a software glitch or a programming error in VZAM that I have had to fix 5 times now (3 program updates and twice to humor tech support when they wouldn't believe me that the problem I was having originated on their end).
This is basically an annoyance and I am extremely glad that VZAM isn't smart enough to be able to access the whole network and change all the settings but I sure would like to see it fixed before someone changes the code in a future update and it allows VZAM to run amok all the way through my LAN network.
Heheheh, it might not stop at the end of my network.....and the whole world will be reset to 192.168.1.1....even the MACs and the Smartphones.
Have Fun

The Strange Case of Change Case

My company's name is MCS. When I'm writing in caps, and then I want to re-use that text in sentence case I use Indesign's change case feature to change caps to sentence case. When ever my company's name is in the copy, I always have to go back and re-write it as upper case. I'm afraid that one day Ill forget to do it.
Is there a setting that I could choose so that this particular combination of letters is always written in caps?

An alternate is to create a text variable and insert it where needed. You can speed up inserting a text variable by using Quick Apply.
Search Google for terms like "InDesign autocorrect tutorial," "InDesign text variable," and "InDesign preferences," without quotes, for details.

The Strange Case of the Missing Network Icon

Can anyone help my buddy Tom - who is running a G4 iBook with OS X Panther? He is unable to get onto his wireless network and here is the problem in his own words:
"Had a moment to muck about in the iBook drive, following data crumbs from the all-pervasive Network software. Apparently, all that spinning of the drive over regions containing bits and bytes of the application managed to cobble together enough of Network to launch an e-mail, which I immediately determined had to go to you. This is strictly a spit-and-string enterprise, similar to a baling wire and soup can exhaust system fix, and likely the only e-mail I'll get off until I complete an entire system restore. Think of it as a faulty telephone connection - you can hear me, but I can't hear you. So, don't bother to respond, as your e-mail will probably languish in my Inbox for the time it takes me to resurrect OS X.
What brought me to this point is my reasoning Network isn't a stand-alone application like a word processor, but rather a "network" (clever, eh?) piece of software with files strewn through other software so they can access various aspects of it. For example, World Book Encyclopedia accomplishes a software update without launching Safari; connecting to its mother ship via but another piece of Network that happens to reside within the program. I guess this approach is what put the "i" in iBook, and it seems to work pretty well...until moments like this. Perhaps Steve Jobs outsourced to Hansel and Gretel to create a new marketing twist.
Anyway, I've talked this all up with a number of people, and the universal response seems to be; "Huh? I've never heard such a thing.". I even managed to mightily confuse Dave and he's got an awful lot of Mac expertise. But the real kicker, when explaining how I reasoned it all out, is when I mention the key to my understanding was when I noticed the missing Network icon. That's when their eyes glaze over and it's apparent they can't quite wrap their brain around the idea. I've deduced how to cajole the Finder to reveal this Archimedean moment, and included a pair of attachments so you, too, can share in my AHA!! revelation. Running this all past Dave had him agreeing I seem to have a handle on it, but the sheer complexity of all those .exec files squirreled here, there, and everywhere still had him scratching his head.
Interestingly, I have to coerce the Finder to display the icon example; you can't simply click it into existence. I do it by plugging in a travel drive, opening same, then ejecting it. The Finder then defaults to what you see (the word Network with no icon).
Speaking of attachments, I was so tempted to wade through all 70 (70!!) e-mails in my inbox, but was fearful my MacGyvered patch would fail before getting this off to you.
Time to fade back into the black hole from whence I came. When I close Safari it'll relinquish its tenuous grasp on the Network .exec file it's hacked to."
Any ideas on what's wrong and how it can be fixed? I'll see that they get passed on to Tom.
G4 Powerbook Mac OS X (10.4.10) iMac

Before the mid-1980s, networking might have been implemented with a lot of goofy little routines (.exec's if you must) calling one another. About that time the CCITT (an international telecommunications standards committee made up of Academic and Industrial representatives) did a lot of work abstracting and then standardizing the functions that various parts of a network perform.
The CCITT refined the notion of a Layered Network Architecture and specified the types of activities performed in each layer. Shortly thereafter Apple implemented Open Transport and delivered it into the marketplace in System 7.5.3.
Apple networking has been very well-behaved and under control since then. It does not tend to "get lost" or "lose track of things". It really is very good. With only a few limitations, you can connect Macs running 7.5.3 through 10.3.9 and have File Sharing work without regard to what versions are talking to each other.

ACS Database Replication over VPN with overlapping Network Addresses

We currently have two co-locations each situated in different provinces. We have two ACS servers which we want to deploy at each co-location. All our network equipments are behind PIX/ASA devices. Getting them to replicate over the VPN should be easy but in our case we have overlapping Network Addresses at both ends of the tunnels.
As per Cisco data does not transit a NAT device when the two Cisco Secure ACS servers communicate and a successful database replication can occur only if the secondary ACS server perceives no change in the IP header or content of the data it receives. So that means we will not be able to Implement NAT to achiever this.
Has any one of you faced this problem of replicating ACS Database over the VPN with overlapping Network Addresses and was anyone able to successfully solve this issue using a work around ?
All provided info and comments are greatly appreciated.

I can help with the 3005 setup if you decide to go that route.
You will need to add 2 network list entries under Configuration>Policy Management>Traffic Management>Network Lists.
You will need to configure a local and remote address. The local will be one of the public ip's for the site.(Provided by your ISP)The remote will be the device you are connecting to on the other end.
You will also need to add a Nat Lan to Lan rule under Configuration>Policy Management>Traffic Management>Nat>Lan to Lan.
Use a static Nat type. The rest will look similar to my example.
Source(Local address)Translated(Public Ip Address used in the network local list)Remote(Ip address of the device on the other end)
Now just create an Ipsec lan to lan tunnel. You will need to agree with the ISP on des type and auth type. Use you local and remote networks you created earlier.

Hi,
I'm working on an Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production With the Partitioning, Real Application Clusters, Automatic Storage Management. It's a 3 nodes RAC: mgvdb01/02/03
After the installation I had to change IP (different IP and Subnet) to the RAC:

Setting up Network Address Server Settings (Static IP)

To be abundantly clear, I do not want to change my Internet Connection Type - its dynamic and will stay that way. I'm not paying my ISP (Time Warner Cable - RoadRunner in NYC) for a static IP address.
I am changing my network address server settigns to disable DHCP, and hopefully assign static IPs to the various comps/devices in my home network. For various reasons (mostly security/ease of use) it would be handy to know my desktop/media center is always (for example) 192.168.1.101, my laptop is always 192.168.1.102, xbox is always...etc etc.
I have DHCP under network address server settings, and attempted to change TCP/IP protocol of my adapters in the comps to static IP (instead of obtain one automatically). I followed the WRT54G router manual whilst doing this. So I inputted the IP for each comp I want to use, 255.255.255.0 for a subnet mask, and the default gateway (in the example, it would be 192.168.1.1, though I want to use a different internal IP address for my network as a security precaution). Now it also wants primary and alternate DNS. TimeWarner won't tell me this information. They say they tell my router it (since its DHCP) and it changes. So...if I want static IP addresses for the devices in my network, I need my router to have a static ip address externally? that means I pay more. Or have I got it wrong? Please advise. I know I could check the router's status page and grab the two DNS servers its currently using, but then when my router's IP and DNSs change due to the internet connection being dynamic, I'd have to go change all the devices in the network (PITA!!). Thank you for your help.

Most ISPs don't actually change their DNSs only the internet IP adress... you can try grabbing those DNS 1 & 2 and set it to your PC. try checking if those will change for verification.
If not, then for primary DNS, use 192.168.1.1 (equivalent for your router so whatever the DNS your router will use, it will just route it. but it doesnt always work), for the alternate DNS: you can use 4.2.2.1 or 4.2.2.2

Local Network Address Change

I have a WRV210 router. I can see it and configure it either manually or through the setup program. If I change the router address from 192.168.0.1 to 192.168.3.1 and reboot both the router and my computer I can access the internet, ipconfig says that 192.168.3.1 is my gateway, but I cannot log on to the router at 192.168.3.1. The MS PD tool says that the connection was rejected by the target. Reset router more than once with the same result.

Hi...
nothing u have to add that ip renge in your network.
how ????
open local area network -- properites - - TCP /IP -- Select properties again ..
it will open a new window.. where u can config ur ip address manually & DCHP ...
select use the following ip add . 192.168.3.4 255.255.255.0 ( ur subnet mas k) 192.168.3.1 ( GW ) 192.168.3.1 ( DNS)
then bottom of the page u can see one advance button click on that one put any ip addres of that range .. like ..192.168.3 .240
save it n reboot ur router ...
n now try to open in web page....

Is there a cups for scanner settings so I can manually change the ip address of a networked scanner?

Here are some facts: I have an ActionTec router from Verizon FiOS that will not support Bonjour bridged from the wireless network to the wired network. Until recently, I was able to scan wirelessly because the HP Printer Scanner (4500, wired network only) was setup prior to my upgrading to Lion. Recently, I had to reinstall the printer driver and re-add the printer in Lion. Without Bonjour support, I was only able to add the printer by connecting my MacBook Pro (2011) to a port on the router. Then, Bonjour allowed me to "add" the printer, and I had both the Print and Scan tabs.
I was able to edit the IP address for the printer manually using cups printers.conf. I can only assume that somewhere in the system, there is a simlar file that keeps track of the IP address for the scanner functionality. Anyone know where that is? My guess is if I can edit the IP address in the scanner settings I'll go back to having wireless scanning ability, too.
Thanks!
rock

I'm not aware of an entry similar to the printers.conf that lists the scanner's connection. The scanner driver plugins are located in /Library/Image Capture/Devices and /Library/Image Capture/TWAIN Data Sources, depending on what scanning applications your device supports. Possibly under the Devices folder will be a HP package and within this could be the entry you are looking for?
Also, if you open System Information and select the Printers entry, you will see the Printer that you created when the Mac was hard wired to the router and it should also show the support for the scanner for this connection. With reference to my Canon MP990 that is wireless, it shows the network address using Bonjour and that scanning is supported, but there is not much else for the scanner entries - apart from a UUID that tells you very little. Also note that the URI only mentions the printer component, so I don't think that having this information will help.
URI: dnssd://Canon%20MP990%20Bonjour._printer._tcp.local./
PPD: Canon MP990 series
PPD File Version: 10.57.2.0
PostScript Version: (3010.000) 705
CUPS Version: 1.6svn (cups-327)
Scanning support: Yes
Scanning app (bundleID path): -
Scanning app version: -
Scanner UUID: FAB77E28-FAB7-7E28-FAB7-7E28FAB77E28
And one last thing to note - the scanner component is not visible in the CUPS web page. Only the printer component can be viewed and modified. So there is not going to be a similar file within CUPS you can modify.

Network Address scheme change - checklist?

I have the arduous task of changing the IP address space within a 24/7 production environment now. The new address space is not within same subnet as is being used currently.
100+ L2 switches, 2 x WAN routers, Core 6509 L3 switch, 800+ hosts, printers, etc.
Is there a good checklist to follow for successful planning and execution?
Setting up secondary IP addresses on sub-interfaces on switches in order to accomplish this with AS LITTLE IMPACT as possible is already in the works.
Any other task checklists, ideas are appreciated.

In addition to Anand's comments...
Generic re-addressing things to look at for potential impacts:
** if you're using it, IOS IP helper addressing for DHCP relaying, etc.
** static routes anywhere (e.g. firewalls, other edges)
** any kind of ACL, route maps, or other filtering in routers, switches, or firewalls
** NAT - e.g. NAT inbound to services
** DHCP server scopes
** DHCP params e.g. default gateway, netmask, etc.
** SLP DA's or other SLP-related infrastructure
** DNS or hosts files
** WINS server(s)
** any servers that have hard to change IP's like NetWare 5.x, 6.0
** anything that uses NDS, eDirectory, Active Directory that stores IP addresses in object attributes (e.g. servers, workstations)
** any AS/400's or mainframes, where touching the LAN interface could potentially kill all open emulator sessions
** any SQL or Intranet/web internally developed stuff where the developer was lazy and hardcoded the IP address instead of using DNS...
** any devices that do LPR/LPD to your printers
** any servers or PCs that participate in routing via RIP (e.g. Windows servers) or that would have static routes defined for some reason
** any SMTP servers that are hardcoded to use IP addresses for relaying and forwarding (to avoid DNS lookup overhead and need to rely on DNS for mail).
** any additional protocols like IPX, APPN, etc. that need to continue to work

Changing the IP Address manually for Laserjet 2100TN

Hi there--
We recently updated all the IP addresses for our LAN to facilitate the set-up of a VPN. Due to problems arising from DHCP address assignment in the past, we maintain addresses manually on the network. Unfortunately this has led to a problem where our old 2100TN is now unreachable on the ethernet network and we are unable to change its IP address; ordinarily this would not be an issue as the Macintosh computers on the network can still find it via AppleTalk, but the PCs are unable to locate it. I tried running HP's network set-up wizard from a PC connected to the network the printer's on and was unable to locate it even when I searched for the printer's hardware address; this was also the case when I connected directly to the printer with an ethernet cable.
Is there any other way to reconfigure the printer's network settings without potentially disrupting our entire network again? Help would be greatly appreciated.

Have you tried changing the printer's IP address manually from one of the Macs that can see it?
I include a copy of a reply on a related subject, from the person on this forum whose user name is IronBadger. Some of it may be helpful. Thank him if it helps.

IronBadger's helpful and informed post begins here:
Since Apple removed AppleTalk from 10.6 it may be slightly more complicated to connect your 5100. But it is possible.
A lot depends on what your internet connection is. Do you use wired or wireless ethernet to connect to the internet? If you are using a wired connection your 5100 will need an IP address that matches your Macintosh. This will involve using the printers control panel to manually assign a TCP/IP address that is in the same range as your Macintosh. Wireless instructions below.
If the Mac has an IP address of 169.254.12.54 and subnet mask as 255.255.0.0, change the IP of the printer to 169.254.12.55, change the subnet mask to 255.255.0.0 and change the Gateway to match what is shown on t he Mac. If your Macintosh gets an IP address directly from your ISP (via DHCP) you may be required to obtain an additional address for the printer.
If you are using wireless (airport) to connect to the internet and just have the printer connected to the Macintosh with wired ethernet the information below should help you get connected.
I have copied a document below that discusses putting the printer on the same network as the Macintosh.
These are the instructions for manually configuring the IP Address on a Macintosh to match an AutoIP generated IP address on a printer.
When some HP LaserJet printers are connected to a network but there is not a DHCP or BOOTP server available it will generate an IP address in the AutoIP range of 169.254.x.x where the last two numbers are derived from the printer's MAC address.
To verify the printer's IP address print a configuration page.
If the printer configuration shows the IP in the Range of 169.254.X.X then the printer has typically self configured an IP address.
If the Macintosh is either not connected to the internet or is not using Built-in Ethernet for internet connectivity the IP address on the Macintosh can be configured to connect to the printer on a local network.
This can also be used to temporarily connect to a printer with no control panel and change its IP address.
Check the IP address on one of the computers on the local network:
1. Click on the Apple menu.
2. Select System Preferences.
3. Select the Network System Preference.
4. Click the TCP/IP tab, click the Configure IPv4 dropdown. and select “Manually.”
5. Change the IP address as mentioned in the following example.
• If the printer has an IP address of 169.254.12.54 and subnet mask as 255.255.0.0, change the IP of the computer to 169.254.12.55, change the subnet mask to 255.255.0.0 and change the Gateway to 0.0.0.0.
Connectivity to the printer can be confirmed by:
Opening the embedded web server using a browser by typing http://<ip address of printer>.
Setting up a print queue for the printer using Print & Fax System Preference.

Local name change on network

Hi everybody.
We have a lot of macbooks with OS mavericks registered to our domain system. Every time we change kind of network (wifi, cable) , a new local name is assigned to our MacBooks.
We tried to modify the file /etc/hostconfig adding "HOSTNAME=-ComputerName- but it doesn't work.
We tried to assign the name through terminal command " scutil --set Hostname..." but it doesn't work too.
Do you have any idea or suggestion to solve this network isssue?
thanks

There are several possible causes for this behavior.
1. Two (or more) computers on the local network have the same Bonjour name, such as "X's-MacBook-Pro.local". Resolve the name conflict by renaming one or more of them in the Sharing preference pane.
2. You have two simultaneous connections to the same local network: probably Ethernet and Wi-Fi. If applicable, disconnect the Ethernet cable or turn off Wi-Fi.
3. A Mac wakes from sleep due to network traffic. This is a bug in OS X that may only affect some models.
4. A device that gets its network address from the router wakes from sleep, and the address it was using before has been assigned to another device.
5. A third-party wireless router has incompatible settings or firmware. In that case, refer to the manufacturer or ISP for support. Restarting the router may help, temporarily.

Changing my IP address.

Does anyone know how I can change the IP address on my powerbook G4 and get a new one?

Your IP address is usually given to your computer by either your Internet Service Provider or Network Administrator (depending on where and how you connect to the internet or network).
If you're connecting from home, chances are that you're assigned a dynamic IP address by your ISP. This can change very time you connect to the internet, or after set intervals. If you're connecting to a network in work, you could be assigned a static IP address or a dynamic one depending on how the network is set up.
So your IP address isn't really something you can just decide to change by yourself. The exception to this is if you're using a router to share an internet connection, say at home. Then your router uses the IP address given by your ISP, and your computers are assigned special IP addresses that only function within your home network. The router then uses Network Address Translation (NAT) to manage the traffic between your computers and the internet. The but even in this case, your best bet is to let your router automatically assign the IP addresses.
If you happen to be in a situation where you have been given a static IP address, you can assign it to your computer in System Preferences as follows:
Click on Network, select your connection (Airport, Ethernet, etc) and click configure. Then click TCP/IP.
Choose "Manually" from the Configure IPv4 menu, and you can enter your IP address in the box that appears below it.
Finally, could I ask why you want to change your IP address? Maybe there's some other work-around someone could suggest that would allow you to achieve the same goal you're thinking about.
