Side note: TCP port 220 uses the Transmission Control Protocol. TCP is one of the main protocols in TCP/IP networks. Whereas the IP protocol deals only with packets, TCP enables two hosts to establish a connection and exchange streams of data. TCP guarantees delivery of data and also guarantees that packets will be delivered on port 220 in the same order in which they were sent. Guaranteed communication over port 220 is the key difference between TCP and UDP. UDP port 220 would not have guaranteed communication in the same way as TCP.
