Internet Protocol (IP) delivers packets between hosts using IP addresses. IP version 4 and 6 are the main versions, with IPv6 addressing increasing the address space to 128 bits. IPv6 addresses are classified as unicast for a single interface, anycast for a group of interfaces, or multicast for multiple hosts. IPv6 supports routing protocols and provides benefits over IPv4 like larger addressing, simpler headers, and improved security. Major organizations like Cisco and the U.S. Census Bureau are transitioning networks to IPv6 as IPv4 addresses become depleted.

Internet Protocol:- IP, as the primary protocol in the Internet layer of the Internet protocol suite, has the task of delivering packets from the source host to the destination host solely based on the IP addresses in the packet headers. IP Addressing:- An Internet Protocol address (IP address) is a numerical label assigned to each device (e.g., computer, printer) participating in a computer network that uses the Internet Protocol for communication. Introduction
IP Version:- Two versions of the Internet Protocol (IP) are in use: IP Version 4
IP Version 6
An Internet Protocol Version 6 address (IPv6 address) is a numerical label that is used to identify a network interface of a computer or other network node participating in an IPv6 computer network. IP v6
Unicast A unicast address identifies a single network interface Anycast An anycast address is assigned to a group of interfaces Multicast A multicast address is also used by multiple hosts IP v6 address classes
An IPv6 address consists of 128 bits 1. Unicast and anycast address format Unicast and anycast addresses are typically composed of two logical parts: a 64-bit network prefix used for routing, and a 64-bit interface identifier used to identify a host's network interface. 2. Multicast address format Multicast addresses are formed according to several specific formatting rules, depending on the application. Address Formats
Unicast and anycast address format:- Note:-Routing prefix size varies bits 48(or more) 16(or fewer) 64 field routing prefix Subnet id interface identifier
General Multicast Format:- Note:-The prefix holds the binary value 11111111 for any multicast address. Multicast address flags Bits 8 4 4 112 Fields Prefix Fig Sc Group id Bits Flag Meaning when 0 Meaning when 1 8 Reserved Reserved Reserved 9 R(Rendezvous) Rendezvous point not embedded Rendezvous point not embedded 10 P(Prefix) Without prefix information Address based on network prefix 11 T(transient) Well known multicast address Dynamically assigned multicast address
IPv6 addresses use 128 bits to represent an address which includes bits to be used for subnetting. The second half of the address (least significant 64 bits) is always used for hosts only. Therefore, there is no compromise if we subnet the network. IP V6 Subnetting Routing Prefix Subnet id Interface id 48 bits 16 bits 64 bits
There exists two forms of routing protocols: 1. Distance Vector Routing Protocol: RIP is Distance Vector Protocols. 2. Link-State Routing Protocol: OSPF and IS-IS are link state routing protocols IP v6 Routing
larger address space (128 bits rather than 32 bits) simplified header format automatic configuration more efficient routing improved quality of service and security compliance with regulatory requirements widespread use in global markets IPv6 includes these benefits over IPv4:
Future of IPv6:- Cisco Systems initially began investigating IPv6 in 2002, but accelerated deploying IPv6 in 2010. They developed a two part strategy that split the project into deploying IPv6 for Ciscos web presence, and deploying IPv6 for Ciscos internal corporate network. The United States Census Bureau is one of the leading implementors of IPv6 within the U.S. government. Charles Sun, IPv6 Transition Manager for the U.S. Census Bureau, provided us with information noting Case Study: IPv6 at Cisco Case Study: IPv6 At The U.S. Census Bureau
