Hi Matthias,

"ipv6only" should be deprecated (ignored) and not removed.

> 2. Use getaddrinfo() instead of gethostbyname().

Agreed, but it should also fall-back to gethostbyname2() and finally to
gethostbyname().

(Are there any systems that have gethostbyname2() but don't have
getaddrinfo()?)

Agreed.

Agreed.

Yeah, I don't see the need for square brackets.

Do you have patch for this? :)
