About ASNs An autonomous system is a network with its own routing policy — an Internet provider, a cloud or a large company — identified by its AS number.
A prefix is a block of IP addresses the AS announces in BGP. A more-specific prefix (indented in the lists) lies inside a larger one.
A BGP neighbour is a network seen next to this AS in routing paths. On the upstream & peer side are typically its transit providers and peers; on the downstream side its customers. BGP carries no such labels, so the sides are inferred.

BGP Neighbours 4 unique neighbours · 2 upstream/peer · 2 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. Upstream & peer side (2) Networks seen to the left of this AS in BGP paths, toward the route collectors — typically its transit providers (upstreams) and peers.

Downstream side (2) Networks seen to the right of this AS in BGP paths — networks whose routes it carries, typically its customers (downstreams).
