reverse ip zone delegation

I've contacted att and had them set our reverse ip zone to be delegated
by our nameservers. I've done a trace with dig and it stops on att's
dns server and I don't understand why. Shouldn't it proceed to query
our nameservers and retrieve the ptr record? I could be totally off
since I am new to this. There is also one other bit of information that
bothers me with the CNAME att has setup. It contains a / as you will
see in the output below. I didn't think this was a valid character, but
again, I am new to this and I could be totally off.
Just as a side note, if I query out nameservers directly (local or
remote) using @ns... I get the expected information back.
Thanks,
J.P.
