As I said before, and many times with this idea, if you need a public IP
all you have to do is request it, the default will be NAT.

I found several state agencies that were running all of their computers
on public IP's, in fact, they had a firewall, but it was setup to pass
ALL traffic in/out without restrictions - funny way of doing it. We
converted them to 32 Public IP natted through the firewall, and then 4
class C segments using private addresses. Took about a week due to some
desktop machines having Fixed IP's.

As a matter of fact, I have done this, and it's not easy. We do it over
a weekend and after staging things during the month before it.
