What is the best rule for blocking all connections to an ip address.   
For example, lets say I want to block all connections to the domain  
google.com.

The domain google.com is not an ip address. If you want to block all web 
access to google, use a transparent cache. Otherwise I see no way to do 
this (reliably).

Google.com was just an example.  Lets say I want to block all  
connections to and from 194.67.57.26.
