My ISP DNS is faster, but the first test was terrible. I will continue using Open DNS for the filters I can you in my house.

“Taking the lowest time and dividing by 1000 tells us the average DNS lookup times from our location in Portland, OR”

Actually this tells us the minimum DNS lookup times. If you want the average you need to add all three of the tests and divide by 3000. This gives:

Google: 73.3ms
OpenDNS: 62.1ms
QwestDNS: 38.0ms

If a DNS server takes an extra one fifth of a second looking up, that doesn’t make any difference at all between them all.

I use Virgin Media in the UK but because my government is always blocking sites and spying on internet users, I rather use something else (along with proxies, VPN’s and all the stuff required to be anonimous on the web).

Starting with OpenDNS, I was very happy with the service untill I hit a wall: Linux Samba X Windows shares. Simply doesn’t work. That is because OpenDNS has a security feature that blocks unresolvable names.

As I couldn’t be bothered to sort out the problem with OpenDNS, I am now using Google DNS – which is not the fastest resolving service but a tenth of a second is nothing to me.

I decided using a free DNS at the moment I tried to access “The Pirate Bay” and my DNS was blocking the site. From then on, I moved on to free DNS and other free services in order to have my privacy intact.

Local ISP is Truvista Communications in SC.

Suprprisingly, google beat all, INCLUDING my local ISP. To top it, I’ve been seeing a lot of recent reliability issues with my ISP’s DNS servers…. I might just be switching…
