Just say, A+P, except that the original proposal of A+P has
wrongly assumed that a NAT box is required inside a site.

Still, surely, port numbers are local-scope names.

However, if the 16bit port numbers are combined with 32bit IP
addresses, they are the globally scoped names with 48 bit
length, which is a lot more than enough to make the Internet
fully end to end transparent even at the current global scale.

Changing TCP is required not for address space extension but
for better handling of multiple addresses for better routing
table aggregation.
