The [link asio.reference.ip__basic_resolver.resolve ip::udp::resolver::resolve()] function is guaranteed to return at least one endpoint in the list if it does not fail. This means it is safe to dereference the return value directly.
Since UDP is datagram-oriented, we will not be using a stream socket. Create an [link asio.reference.ip__udp.socket ip::udp::socket] and initiate contact with the remote endpoint.
