Apache and several other open source projects have converted
their code from using gethostbyname() to using getaddrinfo().

They call getaddrinfo with a hints.ai_family = AF_UNSPEC,
which means "get me both IPV4 as well as IPV6" addresses.

If I were using gethostbyname(), then I could prevent going
to the nameserver if I have the host in the /etc/hosts file
and had /etc/netsvc.conf contain "hosts= local,bind".

How do I create the same behaviour for IPV6 addresses ?

Additionally, I noted that even though I specify a FQDN in
the getaddrinfo() call, it tries both that name as well as
a name created by appending my domain name. For example:
- I specify XXX.YYY.COM
- getaddrinfo does IPV6 queries for:
XXX.YYY.COM
XXX.YYY.COM.YYY.COM
Is this correct behaviour???
