Provenance
Where this comes from
Derived from routing tables collected at 2026-11-02 10:00 UTC by route-views2,rrc00, as seen from 76 BGP vantage points across 74.44M route entries. These are observations from those vantage points, not a complete or authoritative view of the internet.
Inferred from path position, not from any declaration by either party. A network appearing here is carrying these routes; whether that is a paid transit arrangement, a backup, or something else is not something routing data can tell you. Adjacency is not the same as peering. Being next to each other in a path covers paid transit, settlement-free peering and customer connections alike, and routing data cannot distinguish them. Treat this as "these networks exchange routes", nothing more specific.
Cross-check against RIPEstat or BGP.tools, which observe from a different and larger set of vantage points.
