IP address for router
I am a new mac user. I bought a mac book pro and and airport device. I"m attempting to set up and I"m getting the flashing amber light. THe diagnostic says my router does't have an IP address. Any suggestions on where to find it?
Hello from the UK.
I am also a new Mac owner and had the same trouble setting up my Time Capsule. Eventually phoned Apple Help Desk which sorted out my problem.
The TC needs to read the IP address from your router. To let it do this you need to power off your router and TC. Wait at least two minutes, longer if you have the patience, and then power up your router, wait until all the lights are on on your router, once you are sure that is stabilised switch on your TC. Now open the airport programme on your MacPro and when it sees your time capsule it should automatically obtain the IP address it needs. Putting in a manual IP address does not seem to work, not for me anyway. This procedure was given to me by Apple Help Desk and it worked first time.
Hope this helps a little.
Best Regards

Airport utility 6.1 change ip address for router
Hi there,
I want to change the IP address for the router from 192.... to 10.....? It doesn't seem possible with the new version of the aiport utility.
Any help would be greatly appreciated.You can change the IP address range that the AirPort Extreme provides as follows:
Open Macintosh HD > Applications > Utilities > AirPort Utility
Click directly on the AirPort Exteme icon
Click Edit in the next small window that appears
Click Network at the top of the next window
Click Network Options at the bottom of the window
Here, you can changet the iPv4 IP address range from 192.168.x.x to 10.0.x.x
Click Save and then click Update to restart the AirPort Extreme
IF....the Network Options button is grayed out, this indicates that the AirPort Extreme is in Bridge Mode. In that type of setup, you have another modem/router or gateway "upstream" on your network. That is is the device that is providing the 192.168.x.x. IP addresses.
The AirPort Exteme simply passes through that network information to connected devices in Bridge Mode, since you only want one router on the network providing IP addresses.
You will need to check with the support folks for your modem/router or gateway if you want to modify the settings on that device. -
Cant find ip address for router
When I try to access the setup page for my router, 192.168.1.1 does not work and neither does 192.168.1.2 any way to find out what the address is. when I type in those address is comes up no such website ect.
Check first what ip address your router is getting. Open your command prompt. All you need to do is click on the START button at the bottom left of your screen. Click on RUN and type in lower case cmd and press enter. Then you will have a black screen or your command prompt. You will see a blinking cursor all you need to do is type in ipconfig and press enter. You will then know what ip address your getting. The default gateway is the address you need to use for you to access your router set-up page.

Core layer switches IP address for routing
For routing process I add a IP address of each Vlans subnet that active on each Access and Distribution switches (Have a port with that Vlan on the switch) to the corresponding Vlan Interface of them.
Which IP address should I add to the Core switch for routing?
Should I add a IP of each vlan that in the LAN to each vlan interface of Core layer switch?
I want run OSPF routing protocol on the LAN.Hello Reza,
>> Which IP address should I add to the Core switch for routing?
if you want to implement a L3 routed core every link betweeen core device and a distribution device is a L3 link with its own IP subnet.
For example if you have 16 distribution pairs and two core switches:
10.10.10.0/30 dis11 to core1
10.10.10.4/30 di12 to core2
10.10.10.8/30 dis21 to core1
10.10.10.12/30 di22 to core2
10.10.10.128/30 disF1 to core1
10.10.10.132/30 disF2 to core2
this under the idea to have not a full mesh between core routers and distribution devices
then you need also a L3 link between the two cores (at least one)
Each L3 device should also have a loopback interface to be used as OSPF router-id and for management purposes (telnet and so on)
you can use /32 loopbacks taken from same block for example
10.255.254.1/32 core1
10.255.254.2/32 core2
10.255.254.3/32 dis11
10.255.254.4/32 dis12
to make the routing function the core switches have to talk OSPF on all links to distribution nodes
router ospf 10
router-id 10.255.254.1
network 10.10.10.0 0.0.0.255 area 0
network 10.255.254.1 0.0.0.0 area 0
network area commands work like ACL statements and first statement starts OSPF on each interface whose ip address belongs to 10.10.10/24 space
Second command is used to advertise its own loopback.
router-id command allows to define the OSPF router-id.
Distribution nodes have to advertise client Vlans and to take part in OSPF communication on point to point link.
if you use a L2 access layer design client vlans are served by distribution nodes.
if you use a L3 access layer design the access layer switches take part in OSPF and have to advertise their own client vlans.
Hope to help

Seperate IP address for router?
I am trying to connect Wi-Fi between my cell phone and computer. To manually connect the two I must enter an IP address. My computer IP ends in .2. The IP address that my cell phone tells me to enter is .3. Neither address wosrks to connect. I have two Airport routers. Do they also haved IP addresses, like .4and .5? Perhaps it is the IP addresss of the applicable router that I should be entering? If so, how do I determine what the IPs are?
Thank you for your reply. They are both connected via Router A. In fact, my cell phone says that it is connected. But my Wi-Fi sycing app is not communcating. The phone"s IP address is shown as unreachable on the app on my computer. I have tried pinging, with no response. I have tried connecting my cell phone via cable to Router A The app's technical support says it must be my network configuration that is the pronlem My netwok consists only of my computer, my daughter's computer, my cell phone and two Airports. My configuration works fine with my other Wi-Fi app (Router A), as well as my daughter's laptop (Router B).

I have an Airport Extreme as my router and am using time capsule to extend the network in my new house. My ISP is only providing me 4-5 ip addresses and wants me to set up my router to issue out new ip addresses for all my devices.How do I fix this?Help.
They said I need to change my settings to NAT settings. I haven't been able to figure out or find anything. I have also spoken to Apple Support on the phone for hours without being able to figure out how to do this ( i don't think he knew much either lol.) Please help me because I've got about 15-20 devices in my house that require to be connected to the internet and this is just making things ridiculously slow and painful for me.
Thanks!It is on DHCP & NAT under router mode yet my isp is still the one issuing ip addresses to my devices instead of the router issuing them
-
Why does my Airport Express say "self assigned IP address"? No IP address for the ethernet, and it is not connecting to my cable router any longer...
Some cable providers.....like mine, a well known company......seem to take anywhere from a few moments to sometimes up to 30 minutes to allow their equipment back at the cable company to fully reset and issue a new fresh connection.
So, it would not hurt to leave things powered down for 15-20 minutes or more when you perform the reset that John Galt suggests. -
Do I need the same ip address for my computer, router and printer?
Do I need the same IP address for my computer, router and printer?
I am trying to reset my router. I have had a lot of problems with "no connection" to my wireless printer. I reinstalled the software and it works for a while.
Also, lose connection a lot on my laptop or it says I am a guest. My cable provider said it is my router.A typical convenient-sized "block" of addresses commonly used is just under 256 addresses. The router almost always is at location xx.yy.zz.1
By default, DHCP will pass out addresses starting at the next address, xx.yy.zz.2 and keep going up toward 254.
By convention, the Address at the end of the range ( xx.yy.zz.255 in this case) is a "magic" address used for broadcast messages, and must not be assigned to an actual device.
To talk to each other easily, the Addresses must "match" in the first three octets of their address, and be different in the last octet, as the above examples do.
When you produce a reference outside that range, such as asking for Apple's web page at:
http://17.149.160.49
It is sent to your Router, which acts as your "agent" in dealing with the Internet. The Router hides your computer's local address and uses its own Public address (provided automatically by your ISP) so send out packets on your behalf, and listen for the answering packets coming back.
When you use a Router that you control, your computer cannot receive unsolicited queries from the Internet at large because the Router's Firewall discards them. Having a Router that you control means you already have the protection of its Firewall, and need not enable the Firewall built-into your Mac. -
I need to change the MAC Address for Airport on MacBook
I have a specific need to change my son's Airport MAC address as his school requires the use of USB network cards that aren't compatible with MACs. These cards are needed because the school's router uses MAC address filtering.
Before we upgraded his Mac to Snow Leopard, we were able to change the MAC address to the MAC address of the useless dongal the school supplied. We basically created an AppleScript program that ran the "sudo ifconfig en1 ether xx:xx:xx:xx:xx:xx" and all was good.
This command no longer works for changing the MAC address. We tried it as root user as well and by typing it into the terminal window as root. After running the command, we can run "ifconfig en1" and it does display the new mac address but when we turn the airport on and try to connect, it just hangs and won't connect.
Our other non-Snow Leopard still works fine after running the commands so I'm guessing Apple disabled this functionality. It's hardly a security issue by being able to change your mac addres.
Is there a new way to accomplish this? I've searched everywhere.
Thanks!Would an easier solution be to provide the school's IT admin with your mac address and have it added? If they can add a block of mac addresses for the usb dongles, they can add more for machines that cannot use the dongle.
Also: "It's hardly a security issue by being able to change your mac address."
While it may not be a security issue for your machine, it is a security for the school network who is using mac address filtering as hopefully only one part of their wireless security.
That being said, have you read this?

I have 2 Airport Extreme Base Stations, 1 is a 5th generation 802.11n and 1 is a 2nd generation 802.11n. I have 2 Extreme Express Base Stations which are 2nd generation 802.11a/n. The idea is to create a network that works throughout my 2 story house and extend into the garage. It's not a large house 1400 sq ft wood construction. The internet feed comes into the Hughes Net modem upstairs. This is where I want the main base station (5th generation). I eventually will connect a network drive and printer to it. I then want to place the second base station in the room directly under the upstairs room where the main base station is and connect my desk top computer to it. In the living room I will have one of the Express Base Stations connected to the Micro Cell and house stereo system. In the garage (50' away from the living room Express Station & 75' from the Main Base Station) I will place the other Extreme Express Base Station to be connected to the garage stereo system. All of this is with the idea to extend the range of my network for all my devices and airplay to my stereo systems.
Ok, so I have a lot of wireless devices. 2 2nd geneartion iPads, 2 iPhone 4s's, 3 Wi-Fi enabled Sony TVs, Apple TV (near the house stereo Extreme Express), AT&T Micro Cell connected to house stereo Extreme Express, Lorex Security DVR system (connected to main base station upstairs), Whole-House DTV Network system,1 Macintosh Quicksilver Desktop computer, 1 MacBook Pro, and 1 Mac AirBook. As you can see I need a lot of DHCP IP addresses.
So, how do I go about setting this all up? I have read countless articles and discussions but I still have conflicts. It usually mostly, but not limited to, effects my wife's AirBook. Not good at all! I used to have a WDS setup but I understand that the 802.11n Airport Extreme's do not support this. And when I try to distribute a range of IP addresses I run into problems. So can someone please help me resolve this headache?Configure the Extreme connected to the Hughes Net modem as your router. In other words in AirPort Utility, Network tab > Router Mode should be set to "DHCP and NAT". It will provide IP addresses to all the devices on your network.
All other AirPort devices on your network should be configured as bridges: Router Mode "Off".
You may want to configure static IP addresses for any equipment that is likely to be permanently installed. For them, there is no reason to have the Extreme issue an IP address, and they can keep the same one forever.
The Microcell may be able to connect to the Express's LAN port such devices that have to handle voice or other real time audio or video streaming are generally best installed using a strictly wired connection. The same applies to the Sony TV and AppleTV. Keep them on a wired LAN served by the Extreme, avoiding any reliance on a wireless link if at all possible.
The way to implement a complex network like yours is to add one device at a time. Ensure it connects reliably, then add another. You have a lot of work to do.
WDS can be implemented even with new Extremes but its performance is likely to be so unacceptable that it would be nothing more than an exercise in frustration for you. -
Have moved to the UK from the US and want to use up credit on existing account. I no longer have those US card details, so whilst I have credit it is asking me for card details I no longer have, There is money to be spent, any suggestions? Also am wanting to use itunes UK so have tried to set up a new account but inspite of putting in UK address it is identifying me as inithe US. Is this to do with the laptop I've brought with me?
In a roaming network, your "main" router is the device that would require port mapping/forwarding to be configured in order to access the IP camera from the Internet. This router is also the one that would be provide the private IP address for the camera which you will want to be a static one.
So as you described your network, the IP cameras should be getting an IP address or you assigned it a static one and this is the address that you would enter in the Private IP address (or equivalent depending on the router used) field when setting up port mapping.
If you are not able to access this camera from the local network, then this should be troubleshot first. -
I recently had a security system installed in my house. One of the features is an EPAD which enables me to have a virtual keypad on my iphone, and computer to operate the alarm system. The technician was not familiar with Mac's and Airports. How do I open port 80 to 80 in my airport and assign a fixed IP address for the EPAD? Apparently this is what is needed to make this work.
There are three ranges of "strictly local" IP addresses reserved for local Network use:
192.168.xxx.yyy
172.16.xxx.yyy
10.xxx.yyy.zzz
What your Router does for you is to act as your agent on the Internet.Your requests are packaged up and forwarded on your behalf, and only when a response is expected is the response returned to your local IP address.
Directing Network Traffic to a Specific Computer on Your
Network (Port Mapping)
AirPort Extreme uses Network Address Translation (NAT) to share a single IP address with the computers that join the AirPort Extreme network. To provide Internet access to several computers with one IP address, NAT assigns private IP addresses to each computer on the AirPort Extreme network, and then matches these addresses with port numbers. The wireless device creates a port-to-private IP address table entry when a computer on your AirPort (private) network sends a request for information to the Internet.
If you’re using a web, AppleShare, or FTP server on your AirPort Extreme network, other computers initiate communication with your server. Because the Apple wireless device has no table entries for these requests, it has no way of directing the information to the appropriate computer on your AirPort network.
To ensure that requests are properly routed to your web, AppleShare, or FTP server, you need to establish a permanent IP address for your server and provide inbound port mapping information to your Apple wireless device.
To set up inbound port mapping:
1) Open AirPort Utility, select your wireless device, and then choose Base Station > Manual Setup, or double-click the device icon to open its configuration in a separate window. Enter the password if necessary.
2) Click the Advanced button, and then click Port Mapping.
3) Click the Add button and choose a service, such as Personal File Sharing, from the Service pop-up menu. -
ARP table not populating mac address for previously reachable IP address
Router has been online and working fine with one BGP neighbor for almost 2 years and no downtime. 2 weeks ago, added a 2nd BGP peer. Everything worked fine for 2 weeks, then all of a sudden yesterday the 2nd BGP peer is disconnected and does not come back. ISP checks and sees everything looks fine on their end. We cannot even ping each other now.
Upon investigation, the ARP table is not even populating the MAC address for the BGP peer IP anymore (same local subnet). Stays "incomplete" in the table no matter what we do, including clearing arp table, changing IP address, etc.
Plug a laptop directly into the 2nd BGP peer FE port and replicate the IP addressing. Laptop cannot ping Router, but Router CAN ping laptop. Check ARP table, but STILL no mac address assigned and now not even the ARP table showing "incomplete".
Thinking it could be the FE interface, switch to the 2nd FE interface and perform same laptop test, this time with arbitrary IP addressing. Now cannot ping each other, no MAC in ARP table.
End up rebooting the router and lo-and-behold, everything is working normally again. 2nd BGP peer peers up instantly.
I should also mention that the 1st BGP peer worked flawlessly throughout, taking all the Internet load and having no issues throughout.
Also, the FE ports for the 2nd BGP peer are on an HWIC FE card plugged into the router. The 1st BGP peer is plugged into the built-in GE interface. 2901 running: c2900-universalk9-mz.SPA.151-4.M4.bin
Lastly, no router resource issues, no error messages, no logs. Just the BGP peer disconnecting.
I have never, in 20 years working with Cisco routers seen something like this before. This is the most fundamental aspect of IP and Ethernet that was not working.
Has anyone ever seen this behavior before??

How to set a static IP address for deskjet 6940dt
I have two HP laptops, both have WIN7, that keep losing the IP address for my 6940dt printer, each time power goes out to router. I have an desktop PC connected to a NetGear router and RCA modem connected to Comcast cable internet. I also have another desktop that connects wirelessly through the router....but this desktop never loses the printer IP address and I can't figure out why it doesn't and my laptops do.
I have had a fellow at the senior center computer club tell me that I need to set a Static IP address to make the laptops connect . I don't know how to do this and I would need someone to explain it in a language that I can understand, like real basic. I have searched the internet but the things I have found have been very complicated to understand.
Can anyone help me?
This question was solved.

You are on the right track - just go to where you were and follow my directions - it all works the same with wired as it does wireless.

Static NAT and same IP address for two interfaces
We have a Cisco ASA 5520 and in order to conserve public IP addresses and configuration (possibly) can we use the same public IP address for a static NAT with two different interfaces? Here is an example of what I'm refering too where 10.10.10.10 would be the same public IP address.
static (inside,Outside) 10.10.10.10 access-list inside_nat_static_1
static (production,Outside) 10.10.10.10 access-list production_nat_static_1
Thanks for any help.
JeffHi Jeff,
Unfortunately this cannot be done, on the ASA packet classification is done on the basis of mac-address, destination nat and route, and here you are confusing the firewall, to which interface does the ip belong to. I haven't ever tried to do it, but it should cause you issues.
Thanks,
