Description: Network Address Translation - Protocol Translation (NAT-PT) specifies an Internet Protocol version 4 (IPv4)-to- Internet Protocol version 6 (IPv6) transition mechanism. This solution attempts to provide transparent routing to end-nodes in version 6 (V6) realm trying to communicate with end-nodes in version 4 (V4) realm and vice versa.

Note: Network Address Translation/Protocol Translation (NAT-PT) is defined in Request for Comments (RFC) 2766 but due to numerous problems, it has been obsoleted by RFC 4966 and recommended to be deprecated to historic status.
