Interested to know how this will show in the IANA v4 address space registry. Will 045/8 soon appear as belonging to ARIN, since it is now not Interop's?
Correct. Also note that the concept of a single RIR managing each /8 only applies under certain circumstances; there are many cases where multiple RIR's manage resources under a given block and work together to make sure that things like in-addr (and RPKI) function. This could easily be the case with this particular address block at some future time, depending on the state of global return policy.
Also makes me wonder if there are historical versions of this registry available. If reclamation of large blocks such as this becomes commonplace, will many of the legacy allocations simply become footnotes? (In the registry document, as well as in history?)
This has already happened in many cases; address blocks previously held by US DoD, BBN, Stanford were returned, held for a period, and then reissued. /John John Curran President and CEO ARIN
