FranceRegistryRIPE NCC

As of 11th November 2026, AS34534 (FBW NETWORKS SAS), a network registered in France with RIPE NCC, originates 23 IPv4 prefixes covering 5.9k addresses and 1 IPv6 prefix. By IPv4 address space that makes it the 14,760th-largest of the 80,743 networks we see originating IPv4, and the 220th-largest of 1,384 in France. It is seen behind 1 upstream network, most often AS49434 (FBW NETWORKS SAS), and in front of 2 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, and 2 prefixes are also originated by another network.

Networks observed one and two hops upstream of AS34534 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.
