Error msg buggin me

[John Ryan]

See if your ISP will let you reverse your own numbers. They probably won't
if you're only paying for 1 IP, but if they gave you a /30 or something and
if they have compassion, they should delegate that subnet to your servers
using classless in-addr.arpa delegation. Take a look at RFC 2317. It's not
as cryptic as it sounds. If they only gave you one number then your only
recourse is to ask your provider if they'll resolve the address in their own
records to point to your host. I think that's what you're trying to
accomplish but I may be misunderstanding.
