SwitzerlandRegistryRIPE NCC

As of 11th November 2026, AS1836 (green.ch AG), a network registered in Switzerland with RIPE NCC, originates 76 IPv4 prefixes covering 492k addresses and 5 IPv6 prefixes. By IPv4 address space that makes it the 741st-largest of the 80,743 networks we see originating IPv4, and the 4th-largest of 746 in Switzerland. It is seen behind 39 upstream networks, most often AS3356 (Lumen (Level 3)) and AS174 (Cogent Communications, LLC), and in front of 23 downstream networks. 99% of its announcements have a valid RPKI ROA, and none are RPKI-invalid. 100% of its routes reach at least 90% of full-feed peers.

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.
