% I am running a copy of CheckPoints MetaIP which is based on BIND. I
% have several domains setup on the DNS servers, and all DNS analysis
% tools (DNS Expert, etc.) report that there are no PTR records
% available. A simple example is the domain polarisfund.com, which has 5
% records total. A rec 12.25.49.181 for www, A rec 12.25.49.181 for @,
% an MX record, and two NS records. I have a reverse zone 49.25.12.in-
% addr.arpa, and it contains a PTR entry for www.polarisfund.com of
% 12.25.49.181. If I use an NSLookup tool to search for a PTR record in
% the domain I get a valid response. What am I missing?

It seems that the zone has not been delegated to you so your zone
is ignored unless you point to your servers. You need to get ATT
to delegate the 49.25.12.in-addr.arpa zone to ns1.forumfunds.com. &
ns2.forumfunds.com.
