[arin-ppml] prop266 - re-framing the discussion

Do we have any evidence that 1) a significant fraction of BGP hijacking (announcement in BGP of address space registered by an RIR to another organization that has not authorized them to use it) is being performed by organizations that have other address space directly registered to them by an RIR?

Or 2) is nearly all hijacking being performed by entities that have no relationship with the RIR?

If 1) is true, then ARIN could theoretically revoke an organization’s registrations if they used address space that was not registered to them. We can of course debate whether we want RIRs to serve as adjudicators of what space RIR members are allowed to announce, but there would at least be something RIRs could do (kick non-cooperators out of the club of RIR registrants) to enforce their decisions if they decided to make them. 

But if 1) is false and 2) is true, then it’s not clear what ARIN could do about a case of BGP hijacking by someone who doesn’t have any ARIN resources registered to them. Can you think of anything we’d actually want ARIN to do in that case?

ARIN’s only authority is to over their registry of who “has” which addresses, so the only thing I can imagine they could do would be to threaten to revoke unrelated registrations from a transit provider who willfully or negligently accepted the BGP announcement of space from an entity it wasn’t registered to. But if tier 1 transit providers aren’t willing to filter, let alone depeer, each other over hijacking today, it seems unlikely they’d be willing to stop accepting formerly legitimate prefixes from a peer or customer network just because ARIN is trying to take that space away to punish the network for accepting an unrelated hijacked announcement.

If this requires expanding the scope of ARIN’s operations or policies, bring that back to the membership (possibly via PPML?) with the accompanying financial & legal analysis, as usual.
