> Your use of the word "ever" only requires a single counterexample.
Congratulations, you've found a major vendor that actually uses
the term. I'll back off on `nobody else' using it; only Linux and
IBM use it. I still think it says something that four of the five
major router vendors we've looked at so far don't use it. It says
even more for your alleged distiction between NAT and `IP masquerading'
that IBM makes the distinction at times, but at other times ignores
it, and even reverses the meanings.
On http://www.as400.ibm.com/encycl/tcpip.htm. They start in with
`NAT provides a technology called IP masquerading,' and then later
say
NAT translates the internal IP addresses to a single specific
IP address using the unique port numbers assigned to the internal
IP addresses.
In http://publib.boulder.ibm.com/pubs/html/as400/ic2924/info/RZAFM042.HTM:
they use the term `masquerading' for translating not to a single
address, but to a pool of several addresses!
You can use NAT to dynamically translate secure client IP
addresses to a reserved pool of registered IP addresses for
communicating with the untrusted network. This is sometimes
referred to as masquerading.
