The post-review asio code has something quite similar which is
also called a 'resolver'. It was added to provide protocol
independence between IPv4 and IPv6, and is likewise based on
getaddrinfo() and getnameinfo(). For example:

  tcp::resolver r(io_service);
  tcp::resolver::query q("boost.org", "http");
  tcp::resolver::iterator i = r.resolve(q);
  tcp::resolver::iterator end;
  while (i != end)
  {
    tcp::endpoint e = *i;
    ...
    ++i;
  }

There's also a resolver::async_resolve() function.

Cheers,
Chris
