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.

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.
