Hi Jimmy,

I would think that IX addresses are used on the public Internet, just
not globally. They're reachable by everybody who peers at that IX and
all of those folks' customers. I'm more thinking about uses that don't
appear on the public Internet at all or are reachable only from inside
one public AS.

For example, if DoD wanted addresses for the SIPRnet today, would it
still be appropriate for ARIN to allocate them? The SIPRnet is a
classified TCP/IP network which is not permitted to swap packets with
the public Internet.

Hi Frank,

Pure curiousity.  I want to know if there are any reasons for the
practice that are still good enough in light of the address shortage.
Whether the answer suggests any policy changes I leave to someone
