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.

IPv4 uses 32-bit addresses which limits the total number of available addresses to around 4 billion, whereas IPv6 was developed to support the continued growth of the internet using 128-bit addresses providing trillions of addresses to meet future demand. IPv4 routes most current internet traffic and assigns each device a unique numerical IP address, while IPv6 offers improvements and was created by IETF to address the looming problem of IPv4 address exhaustion.IPv4 and IPv6

IPv4 and IPv6 are different versions of the Internet Protocol. IPv4 uses 32-bit addresses which limits the available number of unique addresses, while IPv6 expanded the address space to 128 bits to accommodate many more devices. IPv6 was developed to replace IPv4 and resolve issues like its diminishing available address space as more devices connect to the internet. Some key differences are that IPv6 addresses are much longer at 128 bits compared to 32 bits for IPv4, IPv6 has a larger address space to allow for more connections, and security features like IPSec are mandatory in IPv6.Internet protocol v6

Internet Protocol (IP) is used to carry data from source to destination hosts across the Internet by providing addressing, fragmentation and reassembly, packet timeouts, and prioritization of traffic. IP uses 32-bit addresses to identify sending and receiving hosts and allows packets to be split into smaller fragments if needed to travel across networks. Routers use the IP Time to Live field to discard packets that have been traveling too long to prevent flooding of networks.IPv6 - The Next next generation protocol

IPv6 is the newest version of the Internet Protocol that provides a 128-bit addressing system to replace IPv4 and address the problem of looming address exhaustion, featuring a vastly expanded address space, simplified header format, and security improvements to meet future networking needs. It was developed by the IETF and became an internet standard in 2017 to support continued growth of devices connected to the internet by providing trillions of addresses for devices using hexadecimal notation groups separated by colons.Networking

IPv6 is the latest version of the Internet Protocol, developed to address the limitations of IPv4, particularly the issue of address exhaustion. It uses 128-bit addresses, allowing for a vastly larger number of unique IP addresses compared to the 32-bit system of IPv4. IPv6 also offers improvements such as enhanced routing efficiency, simplified packet handling, and the elimination of the need for Network Address Translation (NAT).subneting-cnnnnnnnnccccccccccccccccc.pdf

IPv4 and IPv6 are both internet protocols enabling device communication, with IPv4 using 32-bit addresses and supporting approximately 4.29 billion unique IPs, while IPv6 uses 128-bit addresses to accommodate the growing number of devices. Key differences include IPv6's built-in IPSec support, absence of a checksum field, and features like packet flow identification and auto-configuration of addresses. IPv6 also replaces certain protocols and functions, including the transition from ARP to NDP and the use of multicast listener discovery instead of IGMP.Ipv4 over ipv6 by Jigar Tarsariya

- 2. 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
- 3. IP Version:- Two versions of the Internet Protocol (IP) are in use: IP Version 4
- 4. IP Version 6
- 5. 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
- 6. 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
- 7. 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
- 8. 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
- 9. 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
- 10. 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
- 11. 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
- 12. 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:
- 13. 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
