I have a code something like this:

TcpConnection::pointer my_conn = GetConn(req);

tcp::socket& my_socket = my_conn->getSocket();

tcp::resolver my_resolver(my_socket.get_executor());

Is it possible to check if the my_socket is ipv4 socket or ipv6 socket?

That depends exactly what you mean by that, but you're likely looking for something like: my_socket.remote_endpoint().address().is_v6() Doxygen doesn't do a very good job at navigating the type templates involved here; using your IDE's code completion is more successful.
