authoritative rDNS

I set up a subnet on my server, complete with rdns, and ARIN has been 
adjusted for my two dns servers ( &

the subnet:

if you do a lookup of, for instance:
and bounce that nslookup off of other dns servers, SOME say:
Authoritative answers can be found from: <ns & ns2>

others, well, at least google do not show anything as
authoritative, altho the IP DOES resolve.

I am curious if isn't trying, or instead, am I missing
something which considers incomplete and therefore 
un-authoritative ?

I just want to make sure my setup is accurate. Thanks.
