BIND 8.3.0 odditiy

[Mark_Andrews at isc.org]

	Looks like their nameservers are broken.  BIND 9.x and BIND 8.3.0 all
	implement EDNS0.  The nameservers in question are returning a NODATA
	response.

	RFC 1035 servers should either ignore the additional record in the
	query or return a error code (SERVFAIL/FORMERR/NOTIMP) depending
	upon the implementation.  There is no way they should be returning
	NOERROR.
