I believe getaddrinfo is the preferred method on all IPv6-capable
platforms.  The code in the boost-review version of asio is using
gethostby{name|addr} but I think this part of the code may be re-worked in
light of various threads I've seen on this list.

The asio host_resolver can be used either synchronously or asynchronously.
In the latter case, resolver calls are handled by a background thread.
