void AnnounceIP();
Description

AnnounceIP opens a UDP socket and transmits a broadcast packet to port 30303. If a computer is on the same subnet and a utility is looking for packets on the UDP port, it will receive the broadcast. For this application, it is used to announce the change of this board's IP address. The messages can be viewed with the TCP/IP Discoverer software tool.
