I believe most prefixes are registered in NTTCOM, but I cannot speak for the myriad of subsidiaries. I believe NTT (like Level3, Savvis, etc) are in a rather rare position having their own IRR, as such maybe not the best material to compare with the other 54281 ASNs out there. > > I'll take your ad-hominem-employer argument > > exuse me! you brought up your employer, not i. and you have not > answered my question.

I don't know why you say this. Does "many operators expressed opinion with their feet" mean that thus "many other operators" should not produce or consume IRR data? Is "many" even relevant in an internet topology that has a noticable cluster as core with tons of stub-edges, in essence being anything but a full mesh? Even if few operators consume IRR data and filter accordingly, depending on their size, it can not only protect their customers and themselves, but large portions of the global system. I ran some calculations just now, comparing public data available to me: should all the RIR's IRR databases cease to exist tomorrow, I estimate that _at_least_ 65,000 customer prefixes would no longer be accepted by NTT's filters (the real number ikely is higher as I did not take into account more-specific pfx/origin covered by registered supernet). I consider these high numbers. Please approach me off-list should you have any further NTT specific questions. (Not only Randy, I'd be happily to elaborate to anyone on how filters are generated and with which parameters!) Randy, your assertation that RIR's IRR are not relevant has been noted. I ask that we continue the discussion about Denis' proposal, under the assumption that RIR's IRRs are relevant. Kind regards, Job
