Chapter44 – IPv6Next generation IP addressinghis section explains how the access to the GarrettCom Magnum MNS-6K can setup usingIPv6 instead of IPv4 addressing described earlier. IPv6 provides a much larger address spaceand is required today by many. IPv6 is available in MNS-6K-SECURE version only.T AssumptionsIthois assumed here that the user is familiar with IP addressing schemes andas other supplemental material on IPv6, configuration, routing, setup andther items related to IPv6. This user guide does not dwell or probe thosedetails.jIntroduction to IPv6IPv6 is short for "Internet Protocol Version 6". IPv6 is the "next generation" protocol orIPng and was recommended to the IETF to replace the current version Internet Protocol,IP Version 4 ("IPv4"). IPv6 was recommended by the IPv6 (or IPng) Area Directors ofthe Internet Engineering Task Force at the Toronto IETF meeting on July 25, 1994 inRFC 1752, The Recommendation for the IP Next Generation Protocol. Therecommendation was approved by the Internet Engineering Steering Group and made aproposed standard on November 17, 1994. The core set of IPv6 protocols were made anIETF draft standard on August 10, 1998.IPv6 is a new version of IP which is designed to be an evolutionary step from IPv4. It is anatural increment to IPv4. It can be installed as a normal software upgrade in internetdevices and is interoperable with the current IPv4. Its deployment strategy is designed tonot have any dependencies. IPv6 is designed to run well on high performance networks(e.g. Gigabit Ethernet, OC-12, ATM, etc.) and at the same time still be efficient for lowbandwidth networks (e.g. wireless). In addition, it provides a platform for new internetfunctionality that will be required in the near future.IPv6 includes a transition mechanism which is designed to allow users to adopt anddeploy IPv6 in a highly diffuse fashion and to provide direct interoperability between IPv4and IPv6 hosts. The transition to a new version of the Internet Protocol is normally72
