IP next generation (IPnG)
IP Next Generation (IPnG) is the collective name used by the Internet Engineering Task Force( IETF) to define a new version of the IP protocol. It is described in RFC 1752.
The goal of the IETF activities was to define successor protocols to the IP protocol with the IPnG prot ocols. This development led to Internet Protocol Version 4( IPv4) in 1981, which is defined in RFC 791. IPnG work focused on the compatibility of the new IP prot ocols with the older versions. In 1991, work began on IPv6, which is an evolution of IPv4. Several proposals were developed between 1992 and 1993, one of which was called IPv5. The IPv6 version was officially introduced as the Internet standard in December 1995. A later proposal bears the designation IPv7.
The goal of all IPnG developments was to be able to use longer IP addresses and thereby cope with the explosive growth of IP addresses on the Internet. In addition, the size of the routing tables became a problem. In addition, other security aspects were taken into account in the new protocols, as were new types of applications and transmission methods with QoS requirements.
