Hey Peter,
I did a google search and found this thread on the freebsd-security list:
http://lists.freebsd.org/pipermail/freebsd-security/2003-April/000127.html
Does that look about right?
Crist J. Clark had a good summary at the end of the thread with what
appears to be causing it.
You don't really include any information about your DNS setup that could
be useful for troubleshooting that, though.
What DNS server/version are you running? Bind 8 or 9 maybe?
I think what you may have been looking for was the /etc/host.conf file.
Hope this is useful.
