This is a stand-alone testbench for testing the axfr (zone transfer) and parsing of the resulting zone. It uses named-xfer to pull the zone from a remote nameserver, parses the zone file, and then displays a dump of the data structure. It should be fairly obvious from the data dump if it worked correctly.

You'll need to allow zone transfers from 67.18.92.50 for this to work.
It currently correctly parses most records, although I still need to test zones with SRV. If you've got a zone with SRV records, or some other unique zone, I'd appreciate a reply with the zone and the nameserver (or PM if you don't want to advertise it).
Thanks,
