Internet Protocol version 6

<networking, protocol> (IPv6, IPng, IP next generation) The most viable candidate to replace the current {Internet Protocol}. The primary purpose of IPv6 is to solve the problem of the shortage of IP addresses. The following features have been purposed: 16-byte addresses instead of the current four bytes; embedded encryption - a 32-bit Security Association ID (SAID) plus a variable length initialisation vector in packet headers; user authentication (a 32-bit SAID plus variable length authentication data in headers); autoconfiguration (currently partly handled by {Dynamic Host Configuration Protocol}); support for delay-sensitive traffic - a 24 bit flow ID field in headers to denote voice or video, etc. One possible solution is based on the TUBA protocol (RFC 1347, 1526, 1561) which is itself based on the OSI Connectionless Network Protocol (CNLP). Another is TP/IX (RFC 1475) which changes TCP and UDP headers to give a 64-bit IP address, a 32-bit port number, and a 64 bit sequence number. RFC 1550 is a white paper on IPng.

dual-stack

<networking> A term used to describe a network node running both IPv4 and IPv6 protocol stacks (or possibly others) at the same time. Such a machine can act as a {protocol converter} between the two networks. (2000-12-19)

IPv6

Internet Protocol version 6 (IPv6) is the most recent version of the Internet Protocol (IP), the communications protocol that provides an identification and location system for computers on networks and routes traffic across the Internet. IPv6 was developed by the Internet Engineering Task Force (IETF) to deal with the long-anticipated problem of IPv4 address exhaustion, and is intended to replace IPv4. In December 1998, IPv6 became a Draft Standard for the IETF, which subsequently ratified it as an Internet Standard on 14 July 2017.

Devices on the Internet are assigned a unique IP address for identification and location definition. With the rapid growth of the Internet after commercialization in the 1990s, it became evident that far more addresses would be needed to connect devices than the IPv4 address space had available. By 1998, the IETF had formalized the successor protocol. IPv6 uses 128-bit addresses, theoretically allowing 2¹²⁸, or approximately 3.4×10³⁸ total addresses. The actual number is slightly smaller, as multiple ranges are reserved for special use or completely excluded from use. The two protocols are not designed to be interoperable, and thus direct communication between them is impossible, complicating the move to IPv6. However, several transition mechanisms have been devised to rectify this.

IPv6 provides other technical benefits in addition to a larger addressing space. In particular, it permits hierarchical address allocation methods that facilitate route aggregation across the Internet, and thus limit the expansion of routing tables. The use of multicast addressing is expanded and simplified, and provides additional optimization for the delivery of services. Device mobility, security, and configuration aspects have been considered in the design of the protocol.

IPv6 addresses are represented as eight groups of four hexadecimal digits each, separated by colons. The full representation may be shortened; for example, 2001:0db8:0000:0000:0000:8a2e:0370:7334 becomes 2001:db8::8a2e:370:7334.

Ejemplos de uso de Internet Protocol version 6

1. "With zero unemployment, nobody is hitting the bench saying, ‘I hope I can find a job one day.‘ " Command Information helps clients upgrade their networks to Internet Protocol Version 6, a higher–capacity system that would enable nearly every device –– including medical dispensers, cars, computers and handhelds –– to connect and work with one another automatically.

2. Unknown to virtually everyone except IT engineers, the internet is being upgraded to a system called IPv6 (for Internet Protocol version 6). Just as you upgrade your mobile phone, computer or any modern appliance, the internet is undergoing a vast, gradual upgrade that will transform how it works and the way we interact with it.
