Speed up DNS lookups
Authored by: ppp on Jun 06, '07 10:25:36AM

Response times using these addresses appear to be twice as long as using my local Comcast supplied servers. dig reports an average of 15ms for SF Comcast vs. 30ms for OpenDNS.

I tested other networks: AT&T DSL 17ms vs. 24ms for OpenDNS, TimeWarner Comm. T1 23ms vs. 9ms for OpenDNS.

It seems that it makes quite a difference depending on your network location, and the performance of your ISP supplied DNS servers. Definitely not universal, but worth looking into.
