Its companion protocol is the Transmission Control Protocol, , and the combination is often denoted TCP/IP.

This tag is also used infrequently to mean the C language structure related to IP addresses, the computational complexity class IP or instruction pointers. It should not be used to refer to intellectual property; that has its own tag, .
