TCP/IP works the same way no matter what country you are from. The terms are
the same, and if someone uses the wrong term, it is not the language
difference, that person just learned the wrong term.

A subnet is what you get when you finish subnetting. One is a noun, one is a
verb. It can only be done the way it was designed to be done. You can do some
very creative things with CIDR now, but that was created more as a way to make
smaller routing tables than any other reason.
