IPv6 Network Architecture Protection
Although there are many perceived benefits to Network Address Translation (NAT), its primary benefit of "amplifying" available address space is not needed in IPv6. In addition to NAT's many serious disadvantages, there is a perception that other benefits exist, such as a variety of management and security attributes that could be useful for an Internet Protocol site. IPv6 does not support NAT by design and this document shows how Network Architecture Protection (NAP) using IPv6 can provide the same or more benefits without the need for address translation.
