IPv6 Prefixes

This AS does not currently announce any IPv6 prefixes.

BGP Neighbours

7 unique neighbours · 4 upstream/peer · 2 downstream · 1 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 (4)

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).

Collector-only (1)

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.
