IPv4 uses a technology known as Network Address Translation (NAT). It has one or more outside addresses and a private network on the inside, using Private class A, B, or C network address space. Some say that there is no longer a need for NAT. Some network admins are considering creating a NAT with IPv4 on the inside and IPv6 on the outside. Some Network Admins are creating NATed networks for IPv6. Please write a post on the subject "Is NAT dead with the implementation of IPv6? Is there a place in IPv6 for NAT? Does NAT add a layer of security for IPv4 and/or IPv6? 400 to 600 words
