SwitzerlandRegistryRIPE NCC

As of 10th November 2026, AS8300 (Swisscom (Schweiz) AG), a network registered in Switzerland with RIPE NCC, originates 7 IPv4 prefixes covering 2k addresses and 7 IPv6 prefixes. By IPv4 address space that makes it the 25,845th-largest of the 80,723 networks we see originating IPv4, and the 243rd-largest of 746 in Switzerland. It is seen behind 2 upstream networks, most often AS3303 (Swisscom (Schweiz) AG) and AS3320 (Deutsche Telekom AG). Every one of its announcements has a valid RPKI ROA, and none are RPKI-invalid. 93% of its routes reach at least 90% of full-feed peers.

Networks observed one and two hops upstream of AS8300 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.
