Strange response for dlci.co.uk.

A few weeks ago, someone asked on comp.unix.solaris about messages from nscd
of the shape
gethostby*.getanswer: asked for "dlci.co.uk IN A", got type "SOA"
There's no great mystery in this because that's what the official servers for
dlci.co.uk (map[1-4].dns.gxn.net) are doing: responding to a request for an
A record with an SOA record in the answer section. (See below for an example.)
However, I am still intrigued by what sort of buggy named or configuration
could cause this, as it's something I don't recall having seen before.

BTW, I tried to report this to the SOA.rname (mail bounces, of course), and
to some likely addresses @dlci.co.uk (which were met only by incomprehesion).
I mention this only to save others the trouble of trying that themselves. :-)
