	RFC 952 was written with the DNS in mind, early versions
	existed when RFC 952 was written.  RFC 952 is NOT obsolete,
	it is very much the current definintion of what is allowed
	in a hostname with one modification from RFC 1123.

	Yes the restrictions were enforced.  3com had a big battle
	even getting the changes in RFC 1123 endorsed.
