	% ping6
	ping6: Non-recoverable failure in name resolution

	The name does properly resolve for AAAA with NOERROR and should
come back with a "hostname nor servname provided, or not known" instead

	% ping6

	The same can be done with source code that goes a getaddrinfo().  
ping6 is just an easy way to reproduce.  I have 450k other domain names 
that return a similar error that are improper.


	Unknown.  A dig/host of the domains does not seem to find this error.
A domain that should return this type of error is www qq com as their
nameserver is doing something 'odd'.
