It's a bit unconventional - and not fool-proof - but functional for now. They added the following information to their name servers:
A) for each IP address a CNAME to the "delegated classless" zone, e.g. In their 69.65.in-addr.arpa. 192.201 CNAME 192.192.201.69.65.in-addr.arpa. 193.201 CNAME 193.192.201.69.65.in-addr.arpa. 194.201 CNAME 194.192.201.69.65.in-addr.arpa. ... Etc 192.201 NS argo21.argohouston.com. 192.201 NS argo22.argohouston.com. B) To match their entries, you need to create your own zone on your name servers: Zone 192.201.69.65.in-addr.arpa. 192 PTR Host192.argohouston.com. 193 PTR Host193.argohouston.com. 194 PTR Host194.argohouston.com. (etc - pick whatever valid host names you desire.)

You'll need to contact swbell.net to have them delegate authority for the reverse DNS to your servers. -Scott --- [This E-mail was scanned for viruses by Declude Virus (http://www.declude.com)] --- This E-mail came from the Declude.JunkMail mailing list.
