NAT indeed can: with ipfilter in NetBSD, for example, you can
translate to a range of addresses:

map ppp0 10.0.0.0/8 -> 209.123.45.0/24

However, I've never heard the term `masquerading' to refer to doing
a translation to only one address. In fact I've never seen the term
`masquerading' at all outside of the Linux community. I'm open to
counter-examples, however.
