14. 14NANOG 21 © 2001, Cisco Systems, Inc. Rationale Behind IPv6 IETF IPv6 (was NG) WG began in early 90 to handle addressing growth issues IP everywhere—data, voice, audio, video integration Looking at few numbers... ~300 million mobile phone users in 1998, 1 billion by 2005 1 billion cars in 2010 with GPS and Yellow Page services Worldwide deployment of Internet appliances Emerging populations/geopolitical China, India, Japan, Russia,… Internet in every school,…
