BGP Neighbours
2 unique neighbours · 2 upstream/peer · 0 downstream. 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. Networks seen to the left of this AS in BGP paths, toward the route collectors — typically its transit providers (upstreams) and peers. Upstream & peer side (2)
