I should take a look at that. What platform are you running on?

Anyway, you can use the name returned by host_name() to do a lookup
using a resolver. E.g.:

  tcp::resolver resolver(io_service);
  tcp::resolver::query query(host_name(), "");
  tcp::resolver::iterator iter = resolver.resolve(query);
  ...

Note: this is not the same as enumerating the network interfaces on
the host. Asio doesn't provide any classes for that.
