BGP Neighbours

53 unique neighbours · 23 upstream/peer · 10 downstream · 28 collector-only. A neighbour can be seen on more than one side. Rows are ordered by AS paths: the number of BGP paths seen by RIPE RIS that contain the adjacency. Sightings count each IPv4/IPv6 route with the adjacency once per RIS peer that sees it (routes × peers), so they show how widely it is seen, not how many distinct routes it carries.

Upstream & peer side (23)

Networks seen to the left of this AS in BGP paths, toward the route collectors — typically its transit providers (upstreams) and peers.

Collector-only (28)

Networks seen to the left of this AS only when they peer directly with a RIPE RIS route collector, so the adjacency may be an artefact of that peering; many of them also appear on the downstream side.
