Jun 17,  · IPV4 Frame Format. Datagram Format The header length can be found by multiplying the value in the HLEN field by 4. Length of data =total length - header length Since the field length is 16 bits, the total length of the IPv4 datagram is limited to 65, (2^16 - 1) bytes, of which 20 to 60 bytes are the header and the rest is data from the upper layer. What two fields below are used by IPv4 and IPv6 respectively to limit the number of times that a packet can be forwarded on a network? hop limit & TTL A globally . Internet Protocol version 4 is the fourth version of the Internet Protocol. It is one of the core protocols of standards-based internetworking methods in the Internet, and was the first version deployed for production in the ARPANET in It still routes most Internet traffic today, despite the ongoing deployment of a successor protocol, IPv6.

The minimum length of an IP header is 20 bytes so with 32 bit increments, you would see value of 5 here. The maximum value we can create with 4 bits is 15 so with 32 bit increments, that would be a header length of 60 bytes. This field is also called the Internet Header Length (IHL). IPv6 Packet Header Format. Payload length – bit unsigned integer, which is the rest of the packet that follows the IPv6 header, in octets. Next header – 8-bit selector. Identifies the type of header that immediately follows the IPv6 header. Uses the same values as the IPv4 protocol field. Hop limit – 8-bit unsigned integer.
