NAT, NAPT, and NAT-PT have been used for some while now to refer to various sorts of address/port translation within an IPv4-only network. Recently, there has been some discussion of network address with IPv6::IPv4 protocol translation. Some have referred to that as NAT-PT also, which can be confusing to some. I'd like to suggest that when talking about the concept of translating protocol versions (IPv6 <-> IPv4) in addition to, or instead of, altering port number or IP address, we use the short-hand notation "NAT+PT".
