  •  I think you're confusing IP with UDP (3+ / 0-)

    TCP and UDP are both layer 4 protocols, aka Transport Layer protocols. Both TCP and UDP sit on IP, or Internet Protocol, which is a layer 3 protocol. (Layer 3 protocols are also known, oddly enough, as an "Internet Layer protocol".)

    Let us all have the strength to see the humanity in our enemies, and the courage to let them see the humanity in ourselves.

      TCP and UDP sit above IP.

      But IPv4 got its number because it was the fourth version of TCP; up through TCP version 3, IP was simply part of TCP.  TCP v4 split off IPv4 in 1978.

      IPv6 was not even the sixth; IP version numbering gets all confused.  You don't want to know.  Suffice to say that IPv6 is simply an EPIC FAIL.
