Isn't this the kind of problems that the Doran filters are supposed to prevent?

Proper PRDB based filters would have stemmed this too. Why isn't everyone using them these days?

Maybe you're thinking RADB, which is based on the distributed Internet Routing Registry, defined by the RIPE folks. Yes, if people define their routes, ASs, and routing preferences in the RADB (or a personal database which they create for their own ISP and make public), then other ISPs can use that information to generate prefix-based configs. The RADB is the database used in the US by providers who do not wish to maintain their own database. CAnet, MCI, and ANS have their own databases. The RIPE database is in use overseas. The PRDB is a years defunct database used by the NSFnet project to configure their routers. Selina P.S. Here's the blurb returned by 'whois -h whois.ra.net' when bogus info is requested: For an overview of the RADB and more information about creating and submitting Route objects, see: http://www.ra.net/RADB.tools.docs/.docs.html ftp://ftp.ra.net/routing.arbiter/radb/OVERVIEW ftp://ftp.ra.net/routing.arbiter/radb/doc/how_to_register ftp://ftp.ra.net/routing.arbiter/radb/doc/updating_maintainers You can obtain the full database files via anonymous ftp: ftp.ra.net:/routing.arbiter/radb/dbase URL: ftp://ftp.ra.net/routing.arbiter/radb/dbase/radb.db.gz
