If you do need the lower-level control, Apple does still recommend `getaddrinfo`. It handles NAT64 translation for IPv6-only carrier networks:

That’s not the current documentation, as evidenced by the “archive” in the URL.

If you want to stay at a lower level the recommendation these days is to use Network.framework. If you want something higher level then use CFNetwork (probably through the classes exported by Foundation like NSURLSession).

I actually found it linked from here, which seems current: https://developer.apple.com/support/ipv6/

It is not best practice to use `getaddrinfo` for DNS resolution, for sure. But it is best practice to use it before connecting to an IP address directly because that address may need to be translated.

I'm actually surprised they suggest getaddrinfo() directly over the async CF wrapper.
