Hello mark.



 ml> (a) Convince comcastbusiness.net to put something into their

I recently did exactly this with comcast.business.net for my
sursum-corda.com domain and had them fix the PTR to reflect
sursum-corda.com on lookup of 173.14.206.213.  All it took was one call and
24 hours and my rDNS problem was solved.

-o-o-o-o-o-o-o-o-CUT-o-o-o-o-o-o-o-o-o-
D:\DIG>host 173.14.206.213 8.8.8.8
Using domain server:
Name: 8.8.8.8
Address: 8.8.8.8#53
Aliases:

213.206.14.173.in-addr.arpa domain name pointer sursum-corda.com.
