RE: Question on 7.0.0.0/8

We checked with IANA, ARIN, and the US DoD regarding 7.0.0.0/8. We were told that this netblock should not see the light of day,

10/8 used to be a DoD address block, but it was also used exclusively in their blacker networks and similar non-connected infrastructure. The result is that 10/8 was opened up for others to use as well. Could we do similar with 7/8? --Michael Dillon
