Question on Blocking an ISP.

As of the last couple weeks, from 1 aol users i have gotten over 1000+ virus emails.
These emails are your tipical freescreensaver virus that has been going around for years now. It seems this person has an affected system. This is not really my question or concern.

I have been scanning though all the headers getting the proxy email servers aol uses, but it seems like a endless list. LOL.

I'm blocking these ips though IPchains, but i really would like to know how to get every class owned by aol so i can block them all.

Receiving mail from aol is no big thing to me, considering 99.9% of the time is junk or spam.

Is there some way to whois arin on a nic handle to get all the classes?

Thank you.
