[VA] What are my Cox DNS Servers?

The dslreports cox dns list is not current and I can't ping what it says is my dns server:

I'm currently using:

According to google, those are West coast servers. I'm in Northern VA.

Anyone have the correct IP's?

I would recommend OpenDNS's DNS servers ( and since switching it's been almost night and day.

I second that. I use OpenDNS: as my primary, but keep and as secondary servers.

BTW, returns a ping time of 8-11 ms. So it can't possibly be on the west coast. Its really close with those times. returns ping of 45 ms. So it is a bit further away, as the bits fly.

28.12 responds to ping in 8 ms for me, and 29.12 responds in 45 ms.

they are different for each area. I use DHCP and get the auto assigned by cox and never have had a problem.

Thanks, I'll switch to OpenDNS and give them a try. The tracert's on Cox's servers get way too high. first hop will be like 40, second jumps to 300's, third is like 60, fourth ranges around the 200's. It's consistent like that too.

I use Cox's DNS with out any trouble... ever... and I trust them more than OpenDNS. If you want to "opt-out" of their enhanced error page (getting re-directed) use these dns servers:,

As of late, I have been having a lot of issues with OpenDNS. I wasn't able to hit a bunch of websites (including Google) on any of my PC's that were setup to use OpenDNS. As soon as I changed those PC's back to Auto (Cox) I was able to hit all those sites without any issues. I've also noticed a lot of stalls using OpenDNS.

Usually I have issues with Cox's DNS Servers, but as of late, the opposite has been true.

if you have a spare pc you can always load up a copy of your favorite linux distro, install bind and then webmin. centos 5.x is really clean for that. minimal install with gnome and then yum bind and webmin. very painless configuration that allows for local dns resolution, dns caching, and root server lookup (or forwarding to your favorite external dns service).

those who forget the past are doomed to repeat it...

Interesting- I haven't seen any OpenDNS problems.

Cox's DNS "local" DNS servers generally follow the naming convention ns1(2).aa.cox.net; with the "aa" being the local network's 2-letter designation.

See: FAQ Listing of Cox 2-Letter Local Codes

Cox NoVA's servers are therefore:
ns1.dc.cox.net -
ns2.dc.cox.net -

(Not sure where those two servers you listed are physically located -- although a tracert to that 2nd one goes thru Dallas)

That said, I too use OpenDNS; w/o any problems to-date.

I said the "2nd one" referring to the two DNS servers listed by the OP (specifically the 29.11 DNS server)

As you can see below, when hitting that server from Northern VA -- hop 8 is in Atlanta while hop 10 is in Dallas.
