So you are OK with a policy that says ARIN is required to revoke address space if other ISP’s choose to accept it into the routing table, but there is no SWIP for it? To me that says you are making a statement about “how things are routed” by requiring a database entry before it gets accepted into routing.

I have no problem with a BCP to the effect that the data SHOULD exist, but as a policy this has ARIN stomping right on the line it claims to avoid.

Tony -

ARIN number resource policy must be germane to administration of the registry;
i.e. if you want a policy that says an address block will only be issued for a certain
reason (and that reason includes some routing characteristic, such as multihoming)
then ARIN will have parties represent that they intend to use in accordance with
that requirement, and will investigate representations that appear to be fraudulent.

For example, a policy that states that "IPv6 blocks will have SWIP performed for any
sub-delegations which are going to be individually announced by the ISP" would be
a policy which is enforceable, since the ISP is representing that they’ll do “X" under
certain circumstances, and it’s trivial to revoke if they fail to follow through and we
receive a fraud report from the community calling attention to that fraud.

Just remember, any characteristic or behavior that you intend to promulgate in this
manner effectively effective defines or extends the scope of ARIN’s mission, so it’s
worth being very cautious and very certain before proposing such…   The fact that
parties need IP address space mean that they have little effective remedy to the
implications of community-developed number policy, and so requirements that aren’t
directly and clearly related to ARIN’s mission (e.g. “requester agrees that they will
put a statute of ARIN’s CEO in their lobby within 12 months of issuance”) are likely
to be found out of scope by ARIN’s Board of Trustees...
