As of 11th November 2026, AS39421 (Sapinet SAS), a content network registered in France with RIPE NCC, originates 6 IPv4 prefixes covering 1.5k addresses and 1 IPv6 prefix. By IPv4 address space that makes it the 31,740th-largest of the 80,743 networks we see originating IPv4, and the 518th-largest of 1,384 in France. It is seen behind 6 upstream networks, most often AS47160 (MOJI SAS) and AS3257 (GTT Communications Inc.), 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.

Networks observed one and two hops upstream of AS39421 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.
