Squid has a special-case for matching IP addresses. If a valid reverse
lookup is registered then this name is used, else the psuedo-domain
"none".
# Deny IP based requests where no reverse lookup is available
acl unknown_ip dstdomain none
http_access deny unknown_ip
# Deny forbidden sites
acl badsites dstdomain playboy.com ....
http_access deny badsites
