It is commonly known as TCP/IP because the foundational protocols in the suite are the Transmission Control Protocol (TCP) and the Internet Protocol (IP). The global coordination of the DNS Root, IP addressing, and other Internet protocol resources is performed as the Internet Assigned Numbers Authority (IANA) functions. This is because an internet header may be up to 60 octets, and the minimum fragment is 8 octets.

Deering, August 1989; RFC 1122, Requirements for Internet Hosts—Communication Layers, IETF, R. 5 contains some external references links from other websites that could change on occasion. The TCP/IP model (Transmission Control Protocol/Internet Protocol) is a model with four layers which is for both modelling current Internet architecture, as well as providing a set a rules that govern all forms of transmission over a network. Due to inclusion of critical devices e. For such purposes this protocol, the Internet Control Message Protocol (ICMP), is used. [3] ICMP poruke su tipično korištene za dijagnosticiranje ili kontrolu, i također se generišu kada se određena greška desi tokom neke IP operacije (specifirano u RFC-u 1122).
