How to improve your Comcast response time?

Recently I switched my ISP from AT&T DSL (I know … what was I thinking) back to Comcast. The process went thru very quick and in 30 minutes my old cable modem was hooked up and provisioned and was seeing 23 Mb/s speeds. with 11ms response time.
But… wait. As soon as I started using it I realized that a lot of web pages were taking forever to load and I quickly remembered the old  Comcast issue. Unreliable/slow DNS servers. And you need the DNS response before you can actually start HTTP transfer and see the page.

There are a lot of free name servers so I will list a few:

OpenDNS: 208.67.222.222, 208.67.220.220  (my choice)
AT&T and Level 3: 4.2.2.1, 4.2.2.2, 4.2.2.3
Google :8.8.8.8, 8.8.4.4

I would  recommend to set the Primary and Secondary from 2 different groups and make these changes on your router so any connected device will inherit the changes.

Problem solved. Happy browsing!

  1. I would also add the OpenDNS.com dns servers
    IP address:
    208.67.222.222
    208.67.220.220

    They allow you to have parental controls via DNS
    That way, if you don’t want your kids ipod surfing xxx sites, you can block it via DNS.
