IMHO, the decision to use private IP space for hosts/routers/interfaces in a network is really a matter of necessity or security. I am familiar with a few corporate networks with nationwide WANs (as well as a major ISP or two) that use 10.0.0.0/8 and other private networks for all their backbone equipment, simply because they lack the public address space to do otherwise. Others do it for the very reason that their equipment is unreachable from the outside world. Whatever the reason, as long as you keep it within your own AS and don't announce or listen to it from anywhere else, there is nothing wrong with setting a network up this way.
No. The assumption that life is as simple as that is the biggest problem with most uses of private IP space.
Another problem is mergers. If you ever merge with another company, hope they dont use the same private IP space. Stb
