Definitions for "IPv6"
Internet Protocol version 6. IPv6 is often touted as the next generation Internet Protocol (IPng). IPv6 is defined by the IETF to replace IPv4 in evolutionary way. The first reason for IPv6 development is the need for more IP addresses to anticipate the growth of the Internet that may include non-traditional network objects, such as mobile phones, automobiles, home appliances, home electronics, humans, pets, trees, etc. In IPv6, IP address is 128 bits long which inflates the number of available IP addresses from 232 to 2128. In today's IPv4-dominated world, NAT has been used successfully to overcome the lack of IP (version 4) addresses. Nevertheless, most new networking products support both IPv4 and IPv6. And it has been predicted that in the long run IPv6 will replace IPv4 because it has inherent QoS support and adds many improvements in areas such as routing, security, and network auto configuration. Also see NAT and QoS.
"Internet Protocol Version 6"( IPv6) is the "next generation" protocol designed by the IETF to replace the current version Internet Protocol, IP Version 4 ("IPv4"). IPv6 fixes a number of problems in IPv4, such as the limited number of available IPv4 addresses. It also adds many improvements to IPv4 in areas such as routing and network auto configuration.
Internet Protocol version 6. Designed by the IETF, IPv6 is the new Internet protocol to replace the current version of Internet protocol, IP version 4 (IPv4). IPv6 has been designed to meet the challenges of the growing Internet and includes several improvements over IPv4. The main benefits of IPv6 include a larger address space, integrated security, support for auto-configuration of terminals, and support for mobility.
