TCP/IP Standards
One of the strengths of the TCP/IP protocol suite is that it is not owned by any one party and is not licensed. This is in contrast to protocols such as AppleTalk and IPX/SPX, which are owned by Apple and Novell, respectively. Because of its non-proprietary nature, TCP/IP has an open development model with its standards published in documents known as Requests for Comments (RFCs). RFCs are maintained by the Internet Engineering Task Force (IETF). You can find RFCs pertaining to TCP/IP on IETF's website at www.ietf.org.
