The PTR record CNAMEs for my /25 allocated prefix are all messed up. They are returning as $ dig +short CNAME 128.168.207.107.in-addr.arpa 128.128/25.168.207.107.in-addr.arpa. Which is obviously a completely invalid DNS entry. I have opened a ticket through the web portal for “prov-dns” but Haven’t gotten a response for 7 days. If anyone from AT&T DNS or knows anyone from AT&T DNS that can help it would be appreciated!
isn't this one of the proper forms of reverse delegation in CIDR land? like: http://support.simpledns.com/kb/a146/how-to-sub-delegate-a-reverse-zone.aspx describes, or in a (perhaps more wordy fashion) in RFC2317? http://tools.ietf.org/html/rfc2317 I think it may be the case that the NS hosts are not prepared for such a domain/record mapping though... the nameservers that would need to to be authoritative for a zone like: 128/25.168.207.107.in-addr.arpa. and have a bunch of PTR records like: 128 IN PTR foo.you.com. 129 IN PTR bar.you.com. etc...
