71Members 69 originate routes
8,744Their routes 92.6% RPKI valid · 92.1% with a route object
52RPKI invalid from 5 members
592No ROA 691 with no route object for their origin
45AS-SET includes own ASN 1 missing it · 1 not found · 12 none
65Route-server members 171 of their 8,645 routes left out by an RPKI + IRR filter

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). 52 routes are RPKI invalid and 159 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.
