Can't specify DHCP DNS server ip with a 255 in it

I tried to add 64.102.255.44 a valid ip addres and a public DNS server to my DHCP configuration but the web interface says ip must be in the range 0-254. How can I report this bug?

Not sure which router you have, but I have a WRT54G V5 that I was able to add that IP address as a Static DNS Server without a problem....
You may need to call the Linksys/Cisco tech support number or use an online chat to report the bug...

DNS Issues, can't set static DNS server

I have an Airport Extreme (which I'll call the router). It has an IPv6 tunnel (to Hurricane Electric), so it hands out IPv4 DHCP and announces an IPv6 network as well. The DNS servers configured on the router are OpenDNS'.
My Apple TV 2 is connected via wired Ethernet to the router. It was using a DHCP address provided by the router, which made the DNS server the same address as the router. I wanted to manually set the DNS to use my ISP's, so that I can make sure the Netflix streaming issue I have is not a DNS issue.
So I changed the Apple TV to a manual address, and set the DNS server to my ISP's DNS server (Apple TV can only have one DNS server? Odd.)
After I save this, the Network page shows the correct manual IP, mask, and router, but the DNS Address is an IPv6 address (one that belongs to my network, but the entire address isn't visible), not the one I set. When I Configure TCP/IP again, and I reach the DNS Address page, the first digit of the existing address is "20", and the rest of the digits are "0". Interesting note as well: if I press Down, the number will increment to 19, and so on, but if I press Up, it changes to 0. Obviously the UI isn't designed for IPv6 addressing, but there's an IPv6 address in there nevertheless.

I have tried to set the DNS Address multiple times now, and have restarted the Apple TV. The IPv6 DNS Address persists.

After 16 hours of working i don´t have seen this easy solution. I had tried with Internet Explorer and Opera but finaly i have need to use Firefox.
Thanks a lot to solve it.

How can I determine what dns server the wifi client use within airport

How can I determine what dns server the wifi client use within airport
I want to use dns servers other then the one that airport extreme is using. For example I got the 172.16.1.1 (the default gateway - airport extreme), but I want to use the office dns servers, that are in a 10.x.x.x range.
Is there a possibility?
Thanks and happy eastern

The Airport Extreme uses the DNS servers assigned by the network that it connects to. Is you Airport Extreme on the 10.x.x.x network? if it is then you are already using the 10.x.x.x DNS servers. Check your Airport Extreme with the Airport Utility and you will see in the Internet tab, the DNS servers used. The devices connecting to the Airport Extreme are assigned a DNS address of the Airport Extremes IP, In your case 172.16.1.1 but all DNS searches and resolution are done with the DNS servers you see in the Airport Extreme.
If you want to use some other DNS then you can override in the Airport Extreme which will be used by all devices connecting too the Airport Extreme, Or you can edit the DNS address in each devices wireless settings.

My airport express can't locate a dns server

I am unable to connect to the Internet, with my Mac,iPad or iPhone, even with the light green. I used my airport utility and it can't find a Dns server.
I called my Internet provider and they said everything looked alright on there end.
Does any body know what it might be?

I would recommend that you do the following as a minimum:
Power-down the modem, AirPort base station, and computer(s).
Power-up the modem; wait at least 10-15 minutes to allow it adequate time to initialize.
Power-up the AirPort base station; wait at least 5-10 minutes. Note: The AirPort's status light may continue to flash amber after it has intialized. That is because, there may be some additional configuration items necessary, like setting up wireless security, before the overall setup is completed to get a green status.
Power-up your computer(s).
If the above steps do not solve the problem, start over with step 1 above, but then perform the next steps between steps 1 & 2. above.
Disconnect the AirPort base station from the Internet broadband modem.
While all of the devices are powered-down, perform a "factory default" reset on the base station. This will get it back to its "out-of-the-box" configuration and make setting it up much easier, especially if you use the "Assist me" process within the AirPort Utility. (ref:Resetting an AirPort Base Station or Time Capsule)
After the base station resets, go ahead and power it back down.
Reconnect the AirPort base station to the Internet broadband modem. For the Extreme and Time Capsule, be sure to connect the cable to the base station's WAN (circle-of-dots) port.
Continue with step 2 in the first set of steps.
In this basic configuration, the AirPort base station will broadcast an unsecured wireless network with a Network Name (SSID) of Apple Network NNNNNN. Network clients, connected to the base station either by wire or wireless, should now be able to access the Internet through the ISP's modem. Once Internet connectivity has been verified, you can use the AirPort Utility to configure the base station for wireless security and any other desired options. Please post back your results.

DNS Server problems with ASA 5505

Hi guys,
we setup a new ASA 5505 which is mainly used as our VPN gateway. The ASA is configured and controlled by our ISP (and this is where the problem starts )) and they somehow cannot manage to get the VPN settings really working.
So, here is our problem.
our machines(Windows 7) are configured to get the network settings through DHCP (Windows 2012 Server).
Before I connect with AnyConnect to our VPN gateway, the DNS Server setting in the network settings for the adapters(IPv4) are set to 'dynamic'
When I now connect, this setting is changes to a statc entry (which is our DNS server).
When disconnecting, it is not reverted back, which means I have to do this always manually.
What I do not understand is the fact, that the DNS server is set for all the adapters, shouldtn't it be only set to the anyconnect adapter?.
The interesting thing is, that when I connect to a different ASA, this does not happen. The ISP is now saying, that the machines are configured exactly the same and that they cannot reproduce, but I can't believe this.
This issue shows up at every machine which connects to our vpn, so it is not only a single machine which might be misconfigured.
Do you have any idea what might cause this issue?
btw, the second ASA (which works) is from our partner company, so we cannot simply copy the config
THanks in advance
Patrick

Nice to see someone from BT has addressed your issue
I have this exact same problem, seems completely bizarre, I'm pretty sure I had the same problem with the original home hub (i have the latest one now). Can you confirm whether the problem does affect anyone with a bt home hub and not just the one that the dyndns is pointing at? I'll try and confirm by hitting your domain from my home connection.

DNS Server Issues with Comcast and Airport Extreme wifi routers

I am having significant challenges with 3 Airport Extreme (latest gen) wifi routers and my Comcast Xfinitity service. It once worked just fine, but now I continually get the blinking amber lights stating "No DNS servers" for each of the Airport Extreme (AE) routers. My configuration is:
Coax cable -> Comcast Xfinity cable modem -> ethernet to 16-port gigabit ethernet switch ->->-> ethernet to 3 Airport Extremes around the house direct connected with switch
I have many wifi devices throughout the house (iPads, MacBooks, home automation devices) as well as direct-connected devices via ethernet (one PC connected to AE router).
Each Airport Extreme router is set with these settings in the Airport Utility app:
Internet tab= Connect using: DHCP
Wireless tab= Network mode: Create a wireless network
Network tab= Router mode: Off (Bridge Mode)
I have attempted to put the Xfinity cable modem in bridge mode, and use the Airport Extreme to serve up the IP addresses, but still lost internet connectivity.
I have also attempted to set the Network tab=> Router Mode to "DHCP and NAT" but get "Double NAT" error issues as well.
I have tried using the Comcast DNS server addresses (75.75.75.75;75.75.76.76) setting on the Internet tab for the routers and do end up getting a green light, but NO internet connectivity.
Lastly, I have tried using the Google DNS servers (8.8.8.8;8.8.4.4) setting on the Internet tab the routers giving me the No DNS servers amber light error and again, no Internet connectivity for either wifi-connected or even ethernet connected (directly to Airport Extreme router) devices (like my PC) despite getting a green light on the router.
Any this point, it really seems that these AE routers are NOT compatible with the Xfinity cable modem or service… (and yes, I've tried power-cycling and restarting the modem, and then the AE routers, MANY times to little avail).
Should I move one of these Airport Extreme wifi routers to before the switch, and have the other 2 in Bridge mode after the switch? Do I need to setup a specific range of DHCP reservation addresses for each different AE router?
Appreciate any insight anyone can share with this aggravating DNS server issue between Comcast & multiple Airport Extreme wifi routers.

I do not see anything wrong with your basic setup.. the issue is indeed the WAN ports of the AE.. AC version are having problems with some network equipment.
You have listed a stack of things you have tried.. but I want you to move the ethernet patch cable you use on each AE to its LAN port instead of WAN.
Restart the airport when you do that.. and then see if it becomes stable.
In bridge mode the airport moves the WAN port to LAN.. but the WAN port setup itself seems more problematic than the LAN ports.
There are other methods we can try if this does not work.. but in the end.. I would be tempted to take the whole lot back to apple.. they need to start making equipment that works with standard modems and switches.
BTW what brand is the 16 port switch?? Does it happen to be managed (smart type)?

DNS fails using router IP address as DNS server address with static IP

This is my first experience with a Linksys router so it might be normal behaviour but just wanted to check. With a WRT54G2 router I have a few PC's I want to use static IP. Up till now with other brand routers including Belkin and Dlink, I have been able to just put the router IP address in as the address of the DNS server when I use static IP. This seemed to work initially with the Linksys but now for some reason, if I don't code the IP addresses of the DNS server provided by my ISP, DNS lookup fails. If I use DHCP for the PC's there is no problem.
Is that normal behaviour or is there something wrong I am doing?
Thanks
Larry

I decided to upgrade my Linksys 54G router to a "Ultra RangePlus Wireless-N Broadband Router (WRT160N)Version 1" . I have had problems with the wireless (as far as I know just wireless portion) connection dropping. I have done some searching I was able to find some settings to try, and it did work better, but not for too long. I have this router within arm reach away, so it's not a distance issue. I have tried many things for about the last 6months or so.
As a last resort, and I do mean last resort and against my better judgement I purchased " Dual-Band Wireless-N Notebook Adapter (WPC600N) Version 1". I was hoping it was a compatibility issue, but there was no difference.
I have heard of trying older firmware, but I can't find any.
I have been a Linksys fan for quite sometime, but as of recently I am thinking of reconsidering if I can't get this resolved with out spending any more money.

How DNS Server works with workgroup machines

Hi All,
I have 1 AD with DNS Server and few machines are in workgroup. I have given my network IP to this machines including Primary, Alternate DNS Server. I am able to use ping -a command to resolve IP address to Computer Name. I have tried to search this workgroup
machines DNS entries on DNS Server but no use.
Please suggest how to check this records & clear stale records
Thanks & Regards,
Amol Bhosale

Hi,
When you join a computer to a domain, the Primary DNS Suffix is automatically configured, which matches the name of the AD DNS domain name, which should also be identical to the DNS zone name. However, workgroup computers normally do not have a Primary
DNS Suffix, unless you’ve already manually configured all of them.
I assume that you didn’t configure the Primary DNS suffix for the workgroup computer, right? That would be the reason that there is no DNS record for the workgroup computer in DNS server.
Please manually
add the primary DNS suffix on the client and check “Use this connection’s DNS suffix in DNS registration” on the workgroup computer in Advanced TCP/IIPv4 Settings, then change the Dynamic Update type to “Nonsecure and secure” in DNS.
If that workgroup computer is DHCP enabled, you can also use DHCP server to force register all leases by following Ace’s article below:
DNS Dynamic Updates in a Workgroup

Leopard DNS Server: Zones with SPF records?

Hi all,
I'm trying to figure out how to setup SPF (Sender Policy Framework) records for some domains I'm currently managing with a Leopard DNS server and I don't see any documentation anywhere. Can someone please tell me if it's even an option? I'm new to running DNS with Leopard, so I could use all the help I can get.
Sincerely,
Israel

Can you give me an example of how it looks in your zone files? I’ve pasted a sample of mine below. Tell me if anything is wrong.
Israel,
I am new to Leopard Server - so I'm no DNS guru. I, too, have not used a DNS setup tool that requires a FQDN just associate an IP with the base of the domain (mydomain.com.). How did you get your 'mydomain.com. IN A 11.22.33.44' accomplished? Did you create a new A record and put mydomain.com. in the Machine Name field?
Here's my setup:
========================
db.mydomain.com
========================
;THE FOLLOWING INCLUDE WAS ADDED BY SERVER ADMIN. PLEASE DO NOT REMOVE.
$INCLUDE /var/named/zones/db.mydomain.com.zone.apple
========================
db.mydomain.com.zone.apple

mydomain.com. IN SOA ns1.mydomain.com. admin.mydomain.com. (

7200 ;Refresh
3600 ;Retry
604800 ;Expire
345600 ;Negative caching TTL
mydomain.com. IN NS ns1.mydomain.com.
mydomain.com. IN NS ns.mydomain.com.
mydomain.com. IN A 64.251.168.218
mydomain.com. IN TXT "v=spf1 ip:64.251.168.218 ip:64.251.168.220 ~all"
www IN A 64.251.168.218
mail.mydomain.com. IN A 64.251.168.220
mail.mydomain.com. IN TXT "v=spf1 a ~all"
xserve.mydomain.com. IN A 64.251.168.218
xserve.mydomain.com. IN TXT "v=spf1 a ~all"
ns IN A 64.251.168.218
ns1 IN A 64.251.168.220
mydomain.com. IN MX 10 mail.mydomain.com.
... where xserve.mydomain.com is my machine's hostname.
I have a funky setup for DNS because I don't have a different, or second, DNS server (just the one on my Xserve with everything else) and my name servers are under this zone. I added the two IPs for my mail and hostname to the base SPF record. Someone could still spoof from using the name or www domains (same IPs) but I can check for it using Postfix up front. I also added "v=spf1 a ~all" in case another mail server tries to check the mailing server or hostname directly.
You'll usually want to set a TXT "v=spf1 ~all" (SPF null) for any records that have no possibility for mail origins, like your ftp and mobile, but it appears you also have a similar issue to me - those services will be running under the same IPs as the mail service. This is why I added "v=spf1 a ~all" to all essential services (mail and hostname). I don't know what will happen if you add an SPF null to an unnecessary service that happens to also have the same IP. (Will the IP get blocked in a cache during a lookup??) So I didn't add an SPF TXT to those domains. I'm a little confused at this point. I should probably read more about it.
http://www.openspf.org/FAQ/Common_mistakes
Also, you'll notice I added FQDN to mail and xserve. If I do this and ensure they are in my reverse DNS PTR records then I've seen that when I add new zone records with same IPs (like for another domain) then the PTR records don't keep switching to the newest entry (why does it do that?).
I don't think your use of the . in the CNAME records is correct. I think the CNAME records are probably unnecessary since you have already fully defined the domains in A records. Also, those A records probably don't need FQDNs (with the ending .). I only added mine for the reason noted above, concerning the PTR records.
I hope someone who knows some more than I can chime in on this.

DHCP & DNS Server 2008

Hello,
I'm not sure how the following is working.
asa5525
anyconnect version 3.1
windows server 2008R2
When you come in via VPN I send clients to the windows server for DHCP/DNS info and records get created in the FLZ and RLZ. When folks disconnect from VPN those records in both FLZ and RLZ get purged instantly. When your on wired and disconnect those records in both zones do not get purged. I have my VPN scope and wired scope setup exactly the same. I'm new to managing DNS and DHCP and know there's a lot to learn but it seems odd that when leaving a VPN session those records fall off right away. I'm not sure if the ASA has something to do with it or the anyconnect client itself.
thanks for any help!

DNS Server problem with AX

my network only consists of the AX, my macbook, and my PC (which is rarely used anymore). At least once a week, sometimes more often, my AX reports a DNS server problem. I've plugged it in to the ethernet and the settings are they same and there is no other router involved. The AX is connected directly from the cable modem. I confirmed with my ISP that the DNS server numbers are correct and they show up in the proper fields as well. What may cause this and how can I fix it?

Welcome to the discussion area!
Since the Express can only use the information that it receives from the ISP,
you might want to try the Open DNS settings to see if that will help. Just be sure to make note of your current settings in case you need to revert to them.
