[VA] DNS..

Hi.. got a curious question. I use OpenDNS for resolution ever since having Cox internet in Roanoke Va. I get a consistent avg ping of 15ms either speedtest.net or pingtest.net. not bad at all but what is the cox DNS servers in roanoke or in virginia?? I was thinking of testing it.
I hear OpenDNS is the way to go.

Actually 4.2.2.1 / 4.2.2.2 is the way to go[unless you enjoy opendns's redirects]

changing DNS will only impact how fast the server will resolve the web address you type in and display the page. you ping like on a speed test or gaming will not be effected by changing dns as ping is more related to routing,distance and the computers at both ends

Is there any reason you prefer Level3/Verizon to Google's DNS? They both use Anycast, but I personally find Google is on the ball with tracking down and resolve the odd DNS issue. I also ran name bench and got a little better performance out of Google DNS, but I imagine everyone's experience is different.

Keep in mind that DNS only affects name resolution, not ping times to a particular host. Certain DNS providers may have an advantage with regards to how long it takes to resolve a hostname however once name resolution is complete DNS is no longer a factor in terms to the path to a given host.

Well if one DNS is returning a IP that is further away then the resolution from a different DNS, then it can effect distance. Also, I find it can effect the time it takes match making to finish and other jobs where the client is sending lots of DNS request over a short amount of time. Overall your right ofcourse, it is no magic bullet. I do see it as a small piece of the puzzle though. JMHO

Larger online services such as your Yahoo, Google, YouTube, etc. do indeed have servers distributed across many geographies. In these scenarios DNS servers are typically configured to return resolve the closest peer geographically to ensure the fastest response time. Using alternative DNS providers can sometimes undermind this effort.

Is using Google's DNS servers 8.8.8.8 & 8.8.4.4 a good choice over the regular Cox DNS servers?

Well I will refer to your better judgement, but I personally have wonderful experiences, both streaming (Youtube,Netflix, Hulu, etc) and gaming (PSN,XBL and Battlenet) using Cox US as my primary DNS and 8.8.8.8 as my secondary. These were the suggestions after using Namebench, a free DNS scanning tool put out by Google. I highly suggest it if people are curious what DNS would work best for them.

Testing your options with Namebench is the place to start, you might also consider putting in a local caching DNS server.

My local DNS has a ping time of 0.510 ms so for cached things it is pretty good. I have it checking OpenDNS where I have a few things blocked.

OpenDNS isn't a bad provider and many of the things they offer can be of value to someone wanting a bit of filtering done at the DNS level. Not foolproof by any means but good enough to provide a bit of a deterrent for folks thinking of visiting sites you have blacklisted. The typo protection is also handy if you type URLs as badly as I do. The free service is enough for many, their paid plans offer more options at a decent price.

ANYTHING is better over cox dns.
many times 1 of 5 "page cannot be displayed" issue and slow youtube can be averted by not using cox dns.

The biggest thing I noticed using Google DNS is youtube is a lot faster.

OpenDNS, Google and several other providers work with various content distribution networks (CDN) to point you to the nearest hosted web content, which is one reason why you may see faster web conetent if you use their DNS resolvers.

See »www.afasterinternet.com for details.

If you create a (free) OpenDNS account and associate your IP then you can configure how the service works, including turning off the suggestion/typo correction/protection/interception/... feature.

thanks for the feedback all. Seems OpenDNS works best for me even better than google's DNS. The reason I brought this up when I had verizon DSL (which I will never have again lol) I used their DNS servers from northern va got great results using it.. even better than using my city's DNS. as a former DSL technician (support) I have found manually plugging in DNS makes the connection more stable than say auto detect DNS.

Lets see: 4.2.2.1 or jump through opendns hoops to get what 4.2.2.1 gives you out the door no hoops required. thanks but no thanks.

But if you want some of the OpenDNS features you can't turn them on with 4.2.1.1 since it doesn't offer them. Me I want the services that OpenDNS provides.

Read their information and see if you like their service and options or you just want a naked DNS and use whatever floats your boat.

This free service meets my needs: »www.opendns.com/home/basic/

More features, no ads but not free: »www.opendns.com/home/vip/

Easy to do for a very basic DNS setup but how do you get it to add features like Geo-tagging and such so you are always given the closest content server's IP?

i've not noticed much of an issue.
using ms-dns on my primary domain controller -- i point to root servers for lookup, all of which are anycast within the us. from there -- the entry is cached for future lookup. aside from things that are cdn-hosted (netflix, youtube, facebook, etc) my lookups are pretty static.

additionally, most of the newer cdn hosting systems that are being used will look at the geo-location of the ip address performing the request, and not just respond based on the location of the dns request from the server. this way -- if you're hitting suboptimal location, it will redirect your request outbound to the correct datacenter/cdn location.
