Something just ain't right here.  First, that works for me on 30+ 
installations.  However, if the user is pointed at an external DNS, you need 
to allow that.  As to how to get the IP addresses of places like google, do 
an "nslookup" like this;

C:\Documents and Settings\Cap'n>nslookup www.google.com
Server:  fw-boat.dnsalias.net
Address:  192.168.64.1

Non-authoritative answer:
Name:    www.l.google.com
Addresses:  64.233.161.104, 64.233.161.99, 64.233.161.147
Aliases:  www.google.com

As to the reasons NOT to add it.  Complexity, and DNS poisoning.  It will 
not be easy, and it will be insecure.
