[ALL] Current list of Cox DNS servers

Updated 11 Nov 2007 @ 6:08 pm CST Thanks to EVERYBODY, regardless of opinion, that contributed to this thread. I hope that our work was worthwhile and some mod or FAQ editor finds it important to save this work.
Thank you to everybody who contributed, even our anonymous friend!

Is this the complete listing of Cox DNS servers that the end-user can see? I ordered it alphabetically based on, which I assume, is a two-letter city designation.

No, just building a list of DNS servers of Cox. I was working on my two DNS servers and started to wonder what DNS servers Cox uses.

I went the DNS FAQ for this forum and it was blank, so I did a search on Google and it turned on the original list that I posted. I then went and looked and found a lot were not on that list so I started this thread to see what other ones were out there.

Why did I do it?
•Fun
•Our Cox DNS FAQ is empty
•So that I can update the forwarders on my DNS servers to my ISP's DNS servers

There is really no reason for a FAQ or anything else on the Cox DNS Servers. Cox uses DHCP and those local DNS Severs will populate the router/internal TCP/IP connection automatically.

There already was an FAQ on Cox DNS servers.
A thread on Cox's DNS servers would fall under the category of "Tech" and "Cox", both recommended for this site and forum, respectively. I see no reason that this thread shouldn't exist unless somebody has a problem with DNS servers being listed, and even then it is public knowledge (open up your TCP/IP settings).

If this thread shouldn't exist then delete it, but it is already #1 on Google out of 928,000 sites:
»www.google.com/search?q=Current+···irefox-a
and I've replicated it on my website; »johnball.wordpress.com/2007/11/1···servers/
I think it would be more of a disservice to not have this listing.

This is my opinion, but I have a feeling you are against this thread Irish Shark See Profile guessing from your first post and then your follow up post. I would really like to know why...

I really don't care about this thread. It just seems to a waste of bandwidth. And as stated above a FAQ is not necessary since Cox uses DHCP.

I find it kind of funny you claim you "really don't care about this thread" but yet you keep popping up in it. Unfortunately for you, you're not the moderator here and it doesn't really matter if you think this thread is worthwhile, or worthless. As I said before, if you think this is a waste, then go somewhere else and quit thread crapping here.

One thing this discussion has yielded us is evidence that Cox is consolidating its DNS servers into one or two data centers rather than having them local to each system. That's interesting, and maybe you don't think that's worthwhile to know, but others here disagree.

Re: [ALL] Current list of Cox DNS servers

I also think it is pretty damn cool when many users pull together, even an anonymous poster, and we determined what BillRoland See Profile said about the consolidation.

At least I learned something new, and I hope others here have as well.

Thanks to EVERYBODY, regardless of opinion, that contributed to this thread. I hope that our work was worthwhile and some mod or FAQ editor finds it important to save this work.

Re: [ALL] Current list of Cox DNS servers

Wow, apparently Baton Rouge and New Orleans has more DNS servers than the two listed, bold are the new DNS servers I found:

68.109.202.20
68.109.202.23
68.109.202.24
68.109.202.25
68.109.202.29

68.109.202.30

Though the 24-29 list as "proxy.[two city letter designation].cox.net" in different areas. I probably would not rely on those for DNS as Cox might be using these for something else and probably not dedicated DNS resolution, but only a Cox rep could tell us.

Curiously it looks like most of these servers are either in Atlanta or Dallas, if the routing is to be believed.

I've always wanted a list of the Cox DNS servers. This is a great idea adding it to the Cox FAQs.

Also, it would be nice if Cox could update us when they change DNS servers, too.... (and why)

FWIW, I just switched from the Cox default DNS servers to 4.2.2.1, 4.2.2.2 and 4.2.2.3 as a test and web surfing seems a bit more snappy (how's that for technical term) to me. Maybe its just my old imagination though...

Re: [ALL] Current list of Cox DNS servers

Typically, you only need to use any two. That is all the space most routers have for DNS server IP address entries. Your NIC may be able to hold three, or more.

Which ones you pick probably only matter in terms of whether they use the "Typo redirect" feature, or not. Secondarily, might be useful to pick DNS servers most closely located to your geographic location.

For those who suggest OpenDNS as an alternative, you are aware that OpenDNS has "Typo redirection" enabled by default? If you don't want that service, the only way to turn it off is to register an account with them (free), and use their "Dashboard" to disable it. They also have some kind of dynamic IP address option which, when enabled, allows them to preserve your selected options in the event your IP address on your CPE is changed by your ISP. Requires a dynamic DNS updater client. Probably not as useful for cable customers whose IP addresses change less frequently that is typical for DSL customers.
