In this case, the list should include the addresses that the report covers ("From 193/8, 194/8, ... under control of the RIPE NCC, these are the block that have been allocated: 193.0.0.0/22, ...).
Well, the general idea is pretty simple and straightforward to implement; you just build up the inverted list of allocated address space. If the RIR is concerned about liabilities, this could easily be provided by a 3rd party. One wonders whether the same list for _assigned_ address space might also be helpful; those filter would obviously have to be updated more regularly or only available in a semi-push fasion like via a eBGP feed in the first place. At least from a RIR perspective, it might provide valuable incentives to at least register used address space correctly. I have been considering issues like these a while ago when I was interested in building a distributed IDS consolidation system with online updated filters. (Similiar to what dshield.org is building up now) But then I got caught up doing something else entirely ;-)
Would do. Also, any other ideas anyone might have would be great. The opposite list (= everything unallocated but under NCC control), with links to the appropriate RIS queries. If one sees an unallocated address then 1 click will allow you to find out who is announcing it.
That would be helpful. Sincerely, Lars Marowsky-Br�e <lmb@suse.de> -- Perfection is our goal, excellence will be tolerated. -- J. Yahl
