SwitzerlandRegistryRIPE NCC

As of 26th September 2026, AS1836 (green.ch AG), a network registered in Switzerland with RIPE NCC, originates 78 IPv4 prefixes covering 493k addresses and 5 IPv6 prefixes. By IPv4 address space that makes it the 729th-largest of the 79,516 networks we see originating IPv4, and the 4th-largest of 739 in Switzerland. It is seen behind 41 upstream networks, most often AS3356 (Lumen (Level 3)) and AS1299 (Arelion (fka. Telia Carrier)), and in front of 23 downstream networks. 99% of its announcements have a valid RPKI ROA, and none are RPKI-invalid. 98% of its routes reach at least 90% of full-feed peers.

Upstream graph

The networks AS1836 is seen behind, one and two hops out, drawn from real AS paths.

Networks observed one and two hops upstream of AS1836 in real AS paths. A thicker line means more vantage points saw that adjacency, so weight tracks how well attested it is — not how much traffic it carries. Adjacency is an observation; whether it is a transit purchase or a settlement-free peering is an inference, and is labelled as one wherever we show it.
