Maybe a neutral, 3rd-party agency to get dumps of tables from major entities and which would send e-mail with suggested aggregations to [email protected] I will make time to start running the route aggregator at routes.netaxs.com again; we've been fighting a random-src-address-SYN-attacker for the last week or two.
