BGP Neighbours

8 unique neighbours · 2 upstream/peer · 0 downstream · 6 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 (2)

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

AS	Name	AS paths	IPv4 sightings	IPv6 sightings
AS33891	CORE-BACKBONE Core-Backbone GmbH	337	3,554	1,312
AS24961	MYLOC-AS WIIT AG	2	22	8

Collector-only (6)

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.
