Depends on your definition of "some".
You can do it with one address - to point your domain to - and some
intelligent inbound proxy setup to redirect requests for a given
port/protocol to a private IP range.

Who says?
I did it once upon a time - 1500 person company, spread over 6 capital
cities in Australia and twice as many office locations - while we had a
complete class C address range available, we used _one_ address -
everything else was done via NAT either inbound or outbound - including
mail, web traffic, and other services.
Worked quite well, considering. And it certainly narrowed down the
potential for inbound hacks to ports WE defined as permitted, not just
open slather.
