| Alternate DNS Servers??? Is it possible to different DNS servers than the Insightbb ones? (63.240.76.4 and 204.127.198.4) Someone posted something a few days ago about using some Sprintlink general DNS servers.
I have all TCP/IP "hardcoded" on my home network. I use static IP addresses, hardcoded gateway (my router), and hardcoded DNS.
Just wondering if any alternate DNS servers might improve reponse times. Also, are there only 2 Insightbb DNS servers?
Thanks in advance...

| Re: Alternate DNS Servers??? Sure you can. You can use any nameserver that will forward queries for you. Here's the list of servers I use in my local nameserver.
204.127.198.4
216.148.227.68
204.127.202.4
63.240.76.4
204.127.198.19
216.148.227.79
63.240.76.19
204.127.199.8
216.148.227.204
204.127.204.8
63.240.76.198
I keep the list limited to nameservers on our network.
204.127.198.4 - ns1.attbi.com.
216.148.227.68 - ns2.attbi.com.
204.127.202.4 - ns5.attbi.com.
63.240.76.4 - ns6.attbi.com.
204.127.198.19 - ns7.attbi.com.
216.148.227.79 - ns8.attbi.com.
63.240.76.19 - ns10.attbi.com.
204.127.199.8 - ns11.attbi.com.
216.148.227.204 - ns12.attbi.com.
204.127.204.8 - ns13.attbi.com.
63.240.76.198 - ns14.attbi.com.
A quick ping based latency test will show you which is most responsive network-wise for you. Unfortunately, it does not show you which respond fastest to query.

| Re: Alternate DNS Servers??? So do you use ALL of these at once? And does it use them all, or is there a priority to the list. Is the first one listed, the primary?
Is there a problem if you use one from another service provider other than Insight?
Thanks again...

| Re: Alternate DNS Servers??? I do use them all, only because I run my own caching nameserver on my local network. You will want to select the ones closest/fastest for you.
ping /n 1 xxx.xxx.xxx.xxx
Do that for each IP, take the 2-3 lowest numbers, they are the most responsive network wise to your location.

| Re: Alternate DNS Servers??? Thanks Robby, I get very fast latency to that server. I'm switching over to it myself as well.
I see 17ms to the speakeasy server listed.
Here's the latency from my insight connection to the nameservers above. None come close to that latency.

| Re: Alternate DNS Servers??? Just to check, I looked up some other speakeasy name servers to see if any others were as low latency as the one robby listed. Sadly, they're not. I'm going to be using the 17ms latency server for sure as my main forwarder as it's half the time of the best attbi. Maybe folks can post other fast nameservers ?
Remember, if you change your DNS to a server off the at&t network, there is no guarantee it will always work. If ever the other site decide they no longer want to forward queries for other IP blocks tat they don't own, the show's over.

Apparently you are. Insight doesn't run any of it's own nameservers.

| Re: Alternate DNS Servers??? Yes. But not promoting the AT&T nameservers - when that is what your company users. Tends to make you wonder if those who work for the company tend to not see value in using those nameservers. It's one of those things of - if the AT&T nameservers are good enough for the customer - why would you want to use another companies? Maybe this makes no sense to you - but makes perfect sense to me.
If you don't value part of the product your employed to upkeep or sell. Why should a customer see value in something you don't as an employee?

I don't know what robbym627 values or doesn't. I do know that someone saying that another dns server, that they don't maintain, has lower latency than another, that they also don't maintain, doesn't really reflect on what they think of the service that they do maintain. That's just me I guess.
Personally, I think you're just jaded at the company and frankly I couldn't imagine giving money to an organization that I felt was screwing me so badly. Other than the IRS of course, who would promptly throw my butt in jail if I stopped. Outside of that, I don't give my money to people/organizations/companies that make me feel the way insight apparently makes you feel.

| Re: Alternate DNS Servers??? BeesTea,
You mention that you run your own DNS Server behind your firewall/router. Can you point me in the right direction to get my own up and running? I have a Solaris Sparc Sun server and would like to get a caching DNS Server up and running. So far I have not yet been able to find a good example of the cache.db etc..... files.
Thanks! | |

| Re: Alternate DNS Servers??? I'm using BIND 9 with split views. One view is for external queries and is a forward with cache. The other is a fake top level domain for my home network (machinename.home.lan). The BIND doc's can get kind of thick.
»www.isc.org/sw/bind/
If you use bind, you can probably get away with using the TLDP docs.
»www.tldp.org/HOWTO/DNS-HOWTO.html
There's also a slew of other caching specific DNS implementations should you not feel like wrestling the BIND bear.

| Re: Alternate DNS Servers??? BeesTea,
Thank you for the info! I will see how it goes. I have tried bind in the past but the documentation is a little to in depth for a beginner like me. Seems that I have the named daemon working but my windows machines do not like it. They complain that:
c:\>nslookup www.google.com
*** Can't find server name for address 192.168.168.9: Non-existent domain
Server: vnsc-bak.sys.gtei.net
Address: 4.2.2.2
Non-authoritative answer:
Name: www.google.akadns.net
Address: 64.233.171.104
Aliases: www.google.com
So I will check my config files again. I know it is something to do with my local domain configuration. Since the solaris server uses the named daemon to service dns lookups without a problem:
ultra10: /var/named: nslookup www.google.com
Server: localhost
Address: 127.0.0.1
Non-authoritative answer:
Name: www.google.akadns.net
Address: 64.233.171.104
Aliases: www.google.com
Thanks again for the documentation. I will look it over and attempt to fix this.

| Re: Alternate DNS Servers??? BeesTea,
Thank you! The site »www.tldp.org/HOWTO/DNS-HOWTO.html was very informative. I now have my BIND caching dns server up and running. I had so many little things wrong it wasn't funny. Now they have been corrected and my DNS server is now working. I just need to "tune" it to the list you have listed above rather than using internic's server list.
Thanks again!

By changing the DNS servers, I have been able to document changes in web browsing.
