It seems OK.

nslookup has always been a lousy tool and is now deprecated. Use dig.

This may be a problem with your resolver (localhost). Because it works
for me:

% dig ANY 129.137.166.203.in-addr.arpa.
...
;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, id: 31030
...

Test with dig and, first, test by querying directly the authoritative
name servers (with the @ syntax), to avoid dependency on your
resolver.
