SwitzerlandRegistryRIPE NCC

As of 11th November 2026, AS39040 (NTS workspace AG), a network registered in Switzerland with RIPE NCC, originates 1 IPv4 prefix covering 1k addresses and 1 IPv6 prefix. By IPv4 address space that makes it the 36,499th-largest of the 80,743 networks we see originating IPv4, and the 349th-largest of 746 in Switzerland. It is seen behind 2 upstream networks, most often AS29075 (IELO-LIAZO SERVICES SAS) and AS33891 (Core-Backbone GmbH), and in front of 16 downstream networks. Every one of its announcements has 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 AS39040 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.
