	NXDOMAIN indicates that there is no entry in the DNS for the
	given name (4.0.168.192.in-addr.arpa).

	If you want to know more than that use dig which prints the whole
	answer.  I also suggest that you query each of the servers in
	/etc/resolv.conf.  They should all be giving the same answer if
	you want consistant results.
