banned IP address

I wish to ban the spammer with the hostname: neg229.named1.com
but I can't convert the hostname to IP address - tried tools such as http://ipfinder.info/scripts/host.php

I'm sure I've seen the answer on this forum but can't find it now I need it.

82.32.30.87

route: 82.32.0.0/12
descr: Telewest Broadband
descr: UK Broadband ISP
origin: AS5462
mnt-by: AS5462-MNT

I did write a mod to make the guestbook store the IP's and not resolve them.

spot on again - thank you carbonize

used the $host = $this->ip; mod
is that correct?

yup
