Route servers: RPKI + IRR filtering
For each member on the route servers: of the routes it originates, how many a route server would leave out if it dropped RPKI-invalid routes and filtered on the IRR the way IXP route servers commonly build their prefix lists: the member's AS-SETs from PeeringDB (with none, its own AS number), expanded as bgpq4 does against whois.radb.net, with more-specifics of a route object accepted down to /24 and /48 (bgpq4 -A -R 24 / -R 48). 27 routes are RPKI invalid and 60 fail the IRR filter. Only each member's own routes are counted: the collectors show a route's origin, not which network it came through, so customers' routes aren't in these numbers. Route objects only in LEVEL3 or IDNIC (no public dump) count as missing.
