Figure 1-3 IPv4 datagram format An IPv4 datagram consists of a header and a data field. The first 20 bytes in the header are mandatory for all IPv4 datagrams. The Options field following the 20 bytes has a variable length. Table 1-4 describes the meaning of each field in an IPv4 datag...
Table 56: Internet Protocol Version 4 (IPv4) Datagram Format Field Name Size (bytes) Description Version 1/2 (4 bits) Version:Identifies the version of IP used to generate the datagram. For IPv4, this is of course the number 4. The purpose of this field is to ensure compatibility between...
IP Datagram General Format Data transmitted over an internet using IP is carried in messages called IP datagrams. Like all network protocol messages, IP uses a specific format for its datagrams. We are of course looking here at IP version 4 and so we will examine the IPv4 datagram format,...

Internet Protocol Packet Format We will now consider the internals of the protocol and discuss its packet format and fields. IP uses 14 separate fields in the packet format. The fields fall into two basic categories.Header management fieldshandle thepacket structure, version, data length, and prot...
