Re: [squid-users] more dns problems

Have you compiled Squid with internal or external DNS?
(default is internal)

If internal, then what TTL is your DNS server returning for these entries?

   dig requested.servername @your.dns.server

If external, then what TTL's have you configured for DNS lookups in

Also, what is the lookups Squid are actually trying to perform? Could it be
that Squid is trying to perform a reverse lookup of the client IP addresses,
and your DNS does not know about the client networks?

A "tcpdump port 53" should tell what kind of lookups are being performed...
