Michael,

As you've already been told, the vast majority of companies do use
NAT, for a number of reasons.

However, I'd also like to point out that NAT is becoming more and
more common for home users. Anyone with more than one computer
is likely to have some small NATing box purporting to be a firewall
so that they can have all computers connected to whatever kind of
broadband Internet access they're using. One common reason for
this is that ISPs charge extra per IP.

Another common reason is that these "internet connection sharing"
boxes often come with NAT enabled by default.
