Atlas returns the 424 most-observed of 1,195; the long tail, seen in a handful of paths each, is left out.

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.

Derived from routing tables collected at 2026-10-13 10:00 UTC by route-views2,rrc00, as seen from 75 BGP vantage points across 73.22M route entries. These are observations from those vantage points, not a complete or authoritative view of the internet.
