Tom –

Most definitely: lack of routing history is not at all a reliable indicator of the potential for valid routing of a given IPv4 block in the future, so best practice suggest that allocated address space should not be blocked by others without specific cause.

Doing otherwise opens one up to unexpected surprises when issued space suddenly becomes more active in routing and is yet is inexplicably unreachable for some destinations.

Using the generally accepted definition of a bogon ( RFC 1918 / 5735 / 6598 + netblock not allocated by an RiR ), 22/8 is not a bogon and shouldn't be treated as one.

The DoD does not announce it to the DFZ, as is their choice, but nothing says they may not change that position tomorrow. There are plenty of subnets out there that are properly allocated by an RiR, but the assignees do not send them to the DFZ because of $reasons.

In my opinion, creating bogon lists that include allocated but not advertised prefixes is poor practice that is likely to end up biting an operator at one point or another.

It has been said before in this thread that the DoD actively uses this
network internally.  I believe if the DoD were to cut costs, they
would be able to do it much more effectively in many other areas, and
their IPv4 networks would be about the last thing they would think of
(along with switching off ACs Bernard Ebbers-style).  With that in
mind, treating the DoD networks as bogons now makes total sense to me.
