WebInternet Protocol version 4 ( IPv4) is the fourth version of the Internet Protocol (IP). It is one of the core protocols of standards-based internetworking methods in the Internet and other packet-switched networks. IPv4 was the first version deployed for production on SATNET in 1982 and on the ARPANET in January 1983. WebIPV6 header format is of 40 bytes in length, contains information essential to routing and delivery, consist of 8 fields, Version, Traffic Class, Flow Label, Payload length, next header, HOP limit, Source address and destination address, where each has its own features and provides essential data required to transmit the data.

WebApr 7, 2024 · 2.Better header format: IPv6 uses a new header format in which options are separated from the base header and inserted, when needed, between the base header and the upper layer data . This simplifies and speeds up the routing process because most of the options do not need to be checked by routers. 3. New options: WebHeader Format. Version: 4-bit IP version number = 6. Prior: 4-bit Priority value. It enables a source to identify the desired delivery priority of its packets, relative to other packets from the same source. Values 0-7 are used to specify the priority of traffic for which the source is providing congestion control, such as TCP traffic.
