The old code says "The method here is to connect a UDP socket to anyone (here to localhost)", but connecting to `localhost` doesn't work because the connection would go via the loopback interface which always has a local address of `127.0.0.1`. The current code works on little-endian platforms due to a mistake in the `createAddress` call. We pass `ntohl(INADDR_LOOPBACK)` as the IP, but since `INADDR_LOOPBACK` is already in host order this actually connects to `1.0.0.127`. Fix the comments and intentionally connect to `1.1.1.1` (as a known public IP address). This also fixes this call for big-endian platforms.
