Port 520

Port 520 is used for the Routing Information Protocol (RIP), which is a protocol used for exchanging network information between routers in a network. It is one of the oldest routing protocols still in use and is commonly used in small to medium-sized networks. RIP works by sending updates about network changes to neighboring routers, allowing them to adjust their routing tables accordingly. Port 520 is used by RIP to send and receive these updates.

Ports those registered with IANA are shown as official ports. The same port number may be unofficialy used by various services or applications. The official usage are listed separately below its usage may change from time to time.
