Prague, CZ · members from IX Report (2026-11-12)

225Members 219 originate routes
62,580Their routes 89.9% RPKI valid · 74.8% with a route object
1,920RPKI invalid from 34 members
4,389No ROA 15,743 with no route object for their origin
149AS-SET includes own ASN 1 missing it · 4 not found · 53 none
199Route-server members 3,434 of their 31,524 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). 1,835 routes are RPKI invalid and 2,927 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.
