This AS is not currently announcing any IPv4 or IPv6 prefixes in the global BGP table (as seen by the RIPE RIS route collectors).
BGP Neighbours
12 unique neighbours · 2 upstream/peer · 10 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. Networks seen to the right of this AS in BGP paths — networks whose routes it carries, typically its customers (downstreams). Upstream & peer side (2)
