I'm having trouble parsing the documentation, and am trying to determine 
if asio supports gethostbyaddr() functionality.

The resolver appears to support hostname to addr queries, but I'm 
looking for addr to hostname (e.g., 127.0.0.1 maps to localhost).

If so, a pointer to an example would be greatly appreciated.

Thanks,
Brian
