I'd better give them a call :)

reverse ip address. I told them when I picked up my fancy new cable
modem that I wanted to IP address to resolve as a certain name. They
setup an n.n.n.n.in-addr.arpa dns record for my static IP supossedly to
stop RBLs from blocking emails.

Thanks for the website tip.
