Um, I'm starting to get a little confused here myself after that reply.

When you are wanting to test the actual destination IP you can use the
'dst' type ACL (squid will do any DNS lokoup needed to find it before
testing).

When you are wanting to test for people sending "CONNECT 1.2.3.4 HTTP/1.1"
etc. then dstdomain (for pre-known IPA), or dstdom_regex (to catch all
IPA) is needed.
