BIND and DDNS

[Kevin Darcy]

Offhand, I don't see anything "corrupted" about that file. It's in BIND "dump" format,
which is somewhat similar to slave replica ("named-xfer") format. It's a text format,
and technically follows the master-file syntax rules, but not really intended to be
user-readable or -manipulable. Since you've enabled Dynamic Update for the zone, you
shouldn't be manually changing it anyway.

Is there anything *functionally* wrong with your DNS?
