I’ve been a long time OpenDNS user (hardcoded in my router), but after installing a new router, I decided to run some tests before reconfiguring its DNS settings. The results – using Google’s own Namebench tool – were surprising.
Comcast wins! (note: 18.104.22.168 resolves to cns.sanjose.ca.sanfran.comcast.net). It is faster than UltraDNS, OpenDNS or Google Public DNS. Surprise, surprise … I guess I don’t have to reconfigure my router after all.
