There are two answers to your question, depending on exactly what you mean. If you want to find out all of the published nameservers (ie, the ones that AOL intends for use by external nodes), then Net::DNS will do what you want - there's an example for finding all of the dns servers for a domain in the main man page. Or, if you mean finding all of AOLs dns servers, including the ones intended for internal use only - well, you'll just have to ask AOL and hope their admins are in a good mood =)
