NAT444 is an IPv4 extension technology being considered by Service
Providers as a means to continue offering IPv4 service to customers
while transitioning to IPv6.  This technology adds an extra Carrier-
Grade NAT (CGN) in the Service Provider network, often resulting in
two NATs.  CableLabs, Time Warner Cable, and Rogers Communications
independently tested the impacts of NAT444 on many popular Internet
services using a variety of test scenarios, network topologies, and
vendor equipment.  This document identifies areas where adding a
second layer of NAT disrupts the communication channel for common
Internet applications.  This document was updated to include the
Dual-Stack Lite (DS-Lite) impacts also.
