But what's the issue in simply sending only the original station's network information into the datagram that's been sent out? If once a response is found, that station can simply just use that information and directly send the response back to the original station by sending just a single UDP response without the need to backtrack through all the stations its visited which would essentially increase the chance of it being lost as well the time the original station to get the response. I don't really understand why it shouldn't be allowed.
