The Transmission Control Protocol is used on TCP port 6667. One of the most important protocols in TCP/IP networks is TCP. TCP allows two hosts to connect and exchange data streams, as opposed to the IP protocol, which only deals with packets.
TCP ensures that data is delivered and that packets on port 6667 are received in the same sequence as they were sent. The guarantee of communication through port 6667 is the main difference between TCP and UDP. In contrast to TCP, UDP port 6667 does not provide the same level of communication assurance.
