How do all the AS's that have their own internal blacklists find out that they should fix their old listings? (Note that this is the exact same problem as "We got blacklisted because of a bad customer, we axed the customer, but we're still blacklisted", which has been a an unsolved problem for decades now).
From the REGISTRY as the ultimate custodian of the IP block.
From Friday's routing table report.
BGP routing table entries examined: 639225 Prefixes after maximum aggregation (per Origin AS): 248678 Deaggregation factor: 2.57 Unique aggregates announced (without unneeded subnets): 307752 Total ASes present in the Internet Routing Table: 56403 As 56,000 AS's all start querying each of the registries (ARIN, RIPE, APnic, LACNIC, and AfriNic) for all 639,000 objects once a day, to see which dozen of those got sold yesterday. Sure, that will work. (And no, the problem isn't the number of http hits on the registries. 35,840,000,000 hits per day is the easy part...)
