[arin-ppml] Draft Policy ARIN-2019-18: LIR/ISP Re-Assignment to Non-Connected Networks

Because of an off-list conversation I'd like to add I think the
expectations of RFC2008 still exist in our policy manual today;
ARIN allocates blocks of IP addresses to ISPs for the purpose of
reassigning and reallocating that space to *their customers.*
22.214.171.124. Contiguous Blocks
IP addresses are allocated to ISPs in contiguous blocks, which should
remain intact. Fragmentation of blocks is discouraged. To avoid
fragmentation, *ISPs are encouraged to require their customers to return
address space if they change ISPs.* *Therefore, if a customer moves to
another service provider or otherwise terminates a contract with an ISP, it
is recommended that the customer return the network addresses to the ISP
and renumber into the new provider’s address space.* The original ISP
should allow sufficient time for the renumbering process to be completed
before requiring the address space to be returned.
Now ARIN's ability to enforce this is very limited, since ISPs can
make reassignments entirely by their own policy without any ARIN review
against NRPM today, we even eliminated ARIN review of large reassignments.
So, I'm not sure a policy change is actually required, as there is noting
ARIN can do about address leases absent connectivity when they are made as
However, I think clarifying that leases without connectivity are valid and
are documented with reassignments and reallocations might return some peace
and quiet to PPML
Also maybe everything after the second sentence of 126.96.36.199 should be
deleted as impractical in a post-free-pool world. That is "To avoid
