As of 29th September 2026, AS766 (Entidad Publica Empresarial Red.es), an access network registered in Spain with RIPE NCC, originates 31 IPv4 prefixes covering 1.4M addresses and 3 IPv6 prefixes. By IPv4 address space that makes it the 379th-largest of the 79,597 networks we see originating IPv4, and the 5th-largest of 926 in Spain. It is seen behind 13 upstream networks, most often AS21320 (GEANT Vereniging) and AS3356 (Lumen (Level 3)), and in front of 22 downstream networks. 79% of its announcements have a valid RPKI ROA, and none are RPKI-invalid. 97% of its routes reach at least 90% of full-feed peers.

Networks observed one and two hops upstream of AS766 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.
