Transit

Downstream networks

inferred

Networks for which AS13000 was observed as the last hop before the origin, meaning it appears to provide them transit.

Provenance

Where this comes from

Derived from routing tables collected at 2026-10-11 10:00 UTC by route-views2,rrc00, as seen from 75 BGP vantage points across 73.47M 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.
