TCP IP Packet Format | Ethernet header,IP header,TCP header IP header: 17-18: T-len: Total length of packet in bytes including IP header: IP header: 19-20: ID: Unique Identification of packet: IP header: 21: Flags: 3 bits (0-DF-MF) DF=0 May fragment,MF=0 last fragment: IP header: 21-22: Offset: Fragment offset in 64 bit blocks: IP header: 23: TTL: Time to live: IP header: 24: Protocol: Upper layer IPv4 header | CCNA An IPv4 header is a prefix to an IP packet that contains information about the IP version, length of the packet, source and destination IP addresses, etc. It consists of the following fields: Here is a description of each field: Version – the version of the IP protocol. For IPv4, this field has a value of 4. Header length – the length of the header in 32-bit words. The TCP/IP Guide - IP Datagram Options and Option Format IP Datagram Options and Option Format (Page 1 of 3) All IP datagrams must include the standard 20-byte header, which contains key information such as the source and destination address of the datagram, fragmentation control parameters, length information and more.In addition to these invariable fields, the creators of IPv4 included the ability to add options that provide additional flexibility IPv4 Packet Structure - The Third Internet

IP Packet Structure - freesoft.org Version: 4 bits. The Version field indicates the format of the internet header. This document … protocol theory - Maximum IPv4 header size - Network The size of the IP header is defined in the IHL (Internet Header Length) which is in 4-7 bits and that means its 4 bits long. if we set all the bits are 1 in Base2 (1111) that would be 15 in Base10. And the the Internet header length is 32 bit words. We multiply 15 x 32 = 480 bits which is equal to 60 bytes (480/8).
