Re: [squid-users] DNS options for Windows port of Squid 2.6

this may be an overkill and somewhat unrelated to squid, but why not
run your own local caching nameserver? this should solve your

http://www.simpledns.com/download.aspx

pretty painless to setup and run. doesn't require many resources
(definitely not with 1 user). you can evaluate it for 14 days, after
that a licence is 79$

I am not affiliated with simpledns in any way.
