IP Protokoll-Nummern

Im Internet Protokoll Version 4 (beschrieben in RFC 793) gibt es ein Protokoll-Feld, das in 8 Bit kodiert wird. Es ermöglicht die Art des Protokolls für den nächsten Level zu erkennen. Die Zuordnung wird von der IANA ( Internet Assigned Numbers Authority) vergeben und ist hier beschrieben.
