The only safe mechanism I could see is that they are not paying the
bill, which the
RIR could tell them. The RIR could send out termination notices, wait
a decent amount of time and
inform IANA. But, how is this different from now ? After all, it says
right in the ARIN policy manual
4.2.1.2. Annual Renewal
An annual fee for registered space is due by the anniversary date of
the ISP's first allocation from ARIN. ISPs should take care to ensure
that their annual renewal payment is made by their anniversary due
date in accordance with the Registration Services Agreement. If not
paid by the anniversary date, the address space may be revoked.
Please review the Annual Renewal/Maintenance Fees Page for more details.
So, it's not clear to me that any action is actually needed here.
For pre-ARIN assignments, you could check for the bankruptcy of the
original assignee, but that would not necessary be safe (companies
may die without going
bankrupt, and, of course, successor entities routinely pick up such
assets).
What you could do, although this will not be politically popular I
suspect, is to start raising the
fees or the burden to get space as exhaustion nears, and then provide
a discount / rebate / easier assignment for companies that recover
lost space. In other words, put the burden on the people that want
the space.
Suppose that if you could show that
- an address block was owned by a bankrupt or defunct entity and
- it had not been advertised since the bankruptcy or for the past
year, whichever is longest and
- efforts to contact the former assignees were fruitless, including
at least some effort by ARIN or
- the previous assignees or their successors had signed a quitclaim
deed.
then, you could get the space. As it gets harder or more expensive
to get "new" space, this would become
more attractive.
