AS199415YORKHOST SAS
As of 27th September 2026, AS199415 (YORKHOST SAS), a network registered in France with RIPE NCC, originates 7 IPv4 prefixes covering 1.8k addresses and 2 IPv6 prefixes. By IPv4 address space that makes it the 29,817th-largest of the 79,523 networks we see originating IPv4, and the 479th-largest of 1,365 in France. It is seen behind 3 upstream networks, most often AS199524 (Gcore S.A.) and AS215114 (Stevan Durand--L'Hours t/a SLBCLOUD). 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.

Upstream graph
The networks AS199415 is seen behind, one and two hops out, drawn from real AS paths.
Networks observed one and two hops upstream of AS199415 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.
