-The problem is that ULTRIX sends so-called ''inverse queries'' (not to be confused with the well-known ''reverse lookups'', which are actually just regular forward lookups to a specific TLD) to map IP addresses to hostnames. Most DNS servers don't support these inverse queries anymore. I have yet to find an implementation that does. Alternatively there might be a way to disable inverse queries in ULTRIX. If anyone knows of either, let me know...

Most DNS servers don't support these inverse queries anymore. Apparently, BIND8 still included an option "fake-iquery" which might be used to support these queries. Versions before BIND8 (4.x) supported IQUERY natively. I have yet to test both variants to see which (if any) of them work.
