ignore_unknown_nameservers

Squid normally checks that DNS replies come from the same IP address to which the query was sent. If the addresses don't match, Squid writes a warning to cache.log and ignores the reply. Some installations use an /etc/resolv.conf trick to query any local name server. If the name server IP address is 0.0.0.0, DNS queries are broadcast on the local area network. The replies, however, come from specific addresses. If you want to use this trick, you must disable the ignore_unknown_nameservers directive.
