A New Internet-Draft is available from the on-line Internet-Drafts directories. Title : NAT444 with ISP Shared Address Author(s) : Y. Shirasaki, et al. Filename : draft-shirasaki-nat444-isp-shared-addr-00.txt Pages : 13 Date : 2008-10-27 This document describes a network model with ISP Shared Address and Carrier Grade NAT (CGN) called NAT444. NAT444 is the only scheme not to require replacing Customer Premises Equipment (CPE) even if IPv4 address exhausted. But it must be noted that NAT444 has serious restrictions i.e. it limits the number of sessions per CPE so that rich applications such as AJAX and RSS feed cannot work well. Therefore, IPv6 which is free from such a difficulty has to be introduced into the network at the same time. In other words, NAT444 is just a tool to make IPv6 transition easy to be swallowed. It is designed for the days IPv4 and IPv6 co-existence.
