Re: Documenting rules for the Private Enterprise Numbers registry: draft-liang-iana-pen-00

Mmm.. In IANA considerations I see:


    o Removal of Private Enterprise Numbers:

    A Contact Name can request to remove the corresponding PEN allocation
    if the resource is no longer in used or the resource does not meet
    the needs.  (In a case when the Contact Name is no longer with the
    Company/Organization, the Modification procedure described above MUST
    be used first.)  Such request does not happen often and regularly.

    Requests can only be fulfilled upon verification by IANA and/or
    subject matter experts.

    If the removal request is honoured, the entry is marked as
    "Unassigned" and can be reallocated by IANA later unless specified
    otherwise, i.e. by marking the entry as "Reserved".

How can we be assured that the once assigned PEN is not being used
anywhere in the digital world? What is someone is still using it in
some obsoleted/no-longer-supported product? Should he/she run the
risk that it conflicts with a possible new assignment/allocation?

I would rather see that it will be marked "returned on yyyy-mm-dd
by xxxxxxx" and then that it not be re-used/allocated unless we
run out of numbers far in the future (at that time we can decide
if this makes sense, or possibly define another arc in
iso.org.dod.internet.private.enterprise, for example:
   iso.org.dod.internet.private.enterprise.2^32-1.PEN
where 2^32-1 is a special PEN that indicates that the PEN
is longer than 32bits.
