FranceRegistryRIPE NCC

As of 11th November 2026, AS215097 (SYSTEM DYNAMICS SARL), a network registered in France with RIPE NCC, originates 1 IPv4 prefix covering 256 addresses and 5 IPv6 prefixes. By IPv4 address space that makes it the 59,976th-largest of the 80,743 networks we see originating IPv4, and the 1,027th-largest of 1,384 in France. It is seen behind 3 upstream networks, most often AS2027 (MilkyWan) and AS41051 (Freetransit Project (Openfactory GmbH)). 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 AS215097 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.
