	Because www.anpe.fr (www.lc.anpe.fr) is being server by a
	load balancer that is not compliant with the base DNS
	specfication.  It doesn't reply to AAAA queries.  While it
	responds to EDNS requests it is obviously not talking EDNS
	properly (the UDP buffer size is just being copied from the
	request).

	Bcc'd dns-admin at sitadelle.com (can't get contacts out of
	whois at the moment).
