Web• IPv4 is the most widely used Network layer protocol • Has been used to run Internet since 1970s • IPv4 addresses are 32 bits long • Written in dotted decimal (4 octets separated by dots) • Each octet represents 8 bits (values between 0 and 255) • Example: 192.168.10.10 IPv4 and IPv4 Addresses Revisited 5 • WebThe major difference in IPv4 and IPv6 packet formats are as follows: 1. IPv6 packet format does not contain header length field as IPv6 base header has fixed length of 40 bytes. IPv4 head is variable in length so header length field is required. 2. The header checksum field is not present in IPv6. factorymedia-japan https://destaffanydesign.com

WebApr 7, 2024 · IP v6 was developed by Internet Engineering Task Force (IETF) to deal with the problem of IP v4 exhaustion. IP v6 is a 128-bits address having an address space of 2^128, which is way bigger than IPv4. In IPv6 we use Colon-Hexa representation. There are 8 groups and each group represents 2 Bytes. The fixed and optional IPv6 headers are followed by the upper-layer payload, the data provided by the transport layer, for example a TCP segment or a UDP datagram. The Next Header field of the last IPv6 header indicates what type of payload is contained in this packet. The payload length field of IPv6 (and IPv4) has a size of 16 bits, capable of specifying a maximum length of 65535 octets for the payload.
