this may be an overkill and somewhat unrelated to squid, but why notrun your own local caching nameserver? this should solve yourproblems: 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, afterthat a licence is 79$ I am not affiliated with simpledns in any way.
