Because of the restrictions put on "residential" accounts, I have a 
Comcast Business account.

With that I have a suit of static IPs and no restrictions.

When I first got the residential account, I found that you can only do 
DNS queries to their name servers.  I needed to be able to test specific 
authoritative name servers.  I also host my own web/email/DNS services.
