The IP protocol header contains the delivery address for the packet and its sender. Since each address is 32 bits (4 octets of 8 bits each), the source and destination IP address takes up 8 bytes TCP/IP Explained. TRANSCRIPT: Today we examine the IP Header in great detail. Protocol (8 bits) Defines the upper layer Protocol. A value of 6 indicates TCP sits on top of the IP datagram Protocol: this 8 bit field tells us which protocol is enapsulated in the IP packet, for example TCP has value 6 and UDP has value 17. Header Checksum: this 16 bit field is used to store a checksum of the..

The need for a protocol identifier (eg. the IP header's Protocol field) in packet-based communication is clear: It's either this or some sort of computationally-intensive inference algorithm This protocol calls on local network protocols to carry the internet datagram to the next gateway or destination host. Gateways implement internet protocol to forward datagrams between networks The IP packet contains several different parts in the header as you have understood from the previous introduction to the IP protocol. The whole header is meticuluously divided into different parts..
