Looks like a rendering of a failed DDNS update in somewhat more human-readable and
succinct terms than the debug output of "nsupdate". I like it.

As for the cause of the error, I'm not sure. "no such domain" usually means
NXDOMAIN, but "nsupdate" never gets an NXDOMAIN as far as I know, since it'll crawl
all of the way up to the root zone if necessary. It may get a REFUSED somewhere
along the line, but not a NXDOMAIN. Then again, maybe DHCPD uses a totally different
algorithm than "nsupdate" does. Maybe you should ask a DHCPD list.
