[ppml] POC verification process

Bill- You are not the one and only that has done this. We did the same
things because we had a company that was resposible for connecting a large
number of seperate 911 dispatch locations. All these locations had already
utilized the private IP space and public IP's were the only way to avoid
Originally I had thought a proposal would have been needed in order to use
the public ips for private use. However, after talking with several board
members I discovered that it wasnt necessary and that use of the IP's this
way was plenty justified.

What each of you who is following an argument similar to Ian's appears
to be missing is that it is a very real problem for enterprises that are
interconnected to avoid conflicting IP space, even within RFC 1918
addresses. In any case, they certainly don't globally coordinate their
use of the private IP space.
It is also not possible to simply grab a slice of public IP space, even
though the networks involved will not connect to the Internet. This is
because the enterprise would lose the ability to communicate with a
piece of the Internet, since they would be routing that slice of
addresses to a private network instead.
At a previous venture, we used a slice of public IP space assigned to us
for a network that would never see Internet-routed packets. The reason
for this was that we were interconnecting the private networks of
multiple customers. Each customer made use of the private IP space, and
their various uses of it conflicted with each other. All of them needed
to get packets to our back end network. The only way to ensure that a
conflict of addressing could be avoided was to use addresses that would
never be used on any customer's private network, and that would never
need to be routed from our own internal network to the Internet. The
only way to do *that* is with a slice of public IP space that we *know*
is never going to be used by anyone else -- one that we had assigned to us.
Do you understand the issue? I happen to think that the idea presented
here is an excellent one, as it handles one of the largest examples of
such a case. I would venture to guess that I was not the first one to
think of doing as we did in my example above....
