	And it was unreachable from all sites that had machines
	named ai.   Just because some resolvers try a single label
	name as is doesn't mean that it is correct.  libbind has
	switches to turn this off.  Absolute single label hostnames
	are not supported (though they may work on some occasions).
	That is why every host was initially placed in the ARPA
	domain.
