Comcast DNS server list?

[Patio]

Can i get a list of up-to-date Comcast DNS server list. I have heard that comcast has regionally distributed dns server. Can i get a complete list? I have come across some old list but my current dns server which is currently working isn't listed so i guess its outdated... help!

Why do you need a list of it? If you are going to use comcast's dns server, let it assign it automatically, this way the best, the closest and the fastest dns server will be assigned automatically...

If you use comcast's internet and you want to configure your router, you can leave the DNS field blank and it will fetch it from the IP assigned to it... So you won't need to manually enter it. If there if no option to leave it blank, just fill 0.0.0.0 and it will be sorted automatically...

My configuration is auto till now and it automatically take the server which is around 200 miles. With this dns server my internet connection drops many times and i don't feel like using the home internet... So i need a list so that i can select the very closest dns server which may avoid the internet dropping...
