Comment (by donn):
My impression is that RFC 3484 (and hence gai.conf) is about order of
address returns, and I don't see any way there to suppress IPV6 queries.
There may be a way to use irs.conf.
The intent behind the "ipv4" flag is to suppress AF_INET6 queries when
getaddrinfo() is called with AF_UNSPEC. I'm stumped by how a service port
would affect that. Empirically, I do get an IPv6 address from
getaddrinfo("www.google.com", "http", ...), followed by one or more IPv4
addresses. (In my present situation with someone's guest wifi, IPv6
queries get answers, instead of timing out.) There is of course a way for
an application to request only AF_INET addresses - the ai_family field -
but my sense is that an application should not be coded to do that. It's
for the host to configure IPv4 or IPv6, and the application should work
either way.
