[DNS] Question about choosing DNS

Apologies in advance if this has been discussed before, but what would be the drawbacks or benefits of configuring my router to use OpenDNS vs using Comcast's supplied DNSSEC service?

Depends on what you want. If you just need name resolution, then there really is no benefit.

if you want the filtering and protection that OpenDNS offers, then there are major benefits.

if you're main concern is about lookup performance, you'll *probably* have best results when using comcasts anycast dns servers... or your own caching dns server that forwards to comcast or google or openDNS

but don't just take my word for it, do your own testing with a tool like dig against the various DNS servers you're looking at using.

i know that sometimes people just want to "stick it to the man" and not use comcast's dns servers out of principle.. they might get stuck with shitty DNS lookup performance by using 3rd party addresses.

But don't forward to Comcast or OpenDNS just use root Hints.

It's a good thing everybody doesn't do this.

Well ya then again anytime your DNS query's TTL is reached a server somewhere has to go back to the roots.

but root hints are meant for larger organizations but it does take the middle man out of the way.
