AS766

AS766 is RedIRIS, Spain's national research and education network (NREN), and it is an actively routed ASN today — not a dormant or legacy holding in any operational sense. RIPE NCC's RDAP autnum record ties it to Entidad Pública Empresarial Red.es, a Spanish public corporate entity reporting to the Ministry of Economic Affairs and Digital Transformation, with a top-level registration event dated 2002-09-16 and a last-changed event of 2026-06-08.

RedIRIS connects more than 500 affiliated Spanish universities and public research centers to the pan-European GEANT network, and the operator holds ISO 9001, ISO 27001, Spain's ENS (Esquema Nacional de Seguridad), and AENOR Responsible AI certifications. Two independent BGP collectors disagree on the exact live prefix count — likely reflecting different measurement windows — but agree closely on total announced address space: roughly 1.37 million IPv4 addresses, on the order of 5,356 /24-equivalents.

Upstream transit runs through Cogent, Lumen/Level 3, GEANT, and Hurricane Electric, corroborated by both bgp.tools and bgp.he.net. RedIRIS peers at four IXPs — CATNIX and ESPANIX in Spain, plus GigaPix in Lisbon, Portugal — with roughly 48 to 55 observed BGP peers depending on source. PeeringDB lists an Open peering policy, though RedIRIS's own site does not publish a dedicated public peering-policy page.

RPKI posture looks generally healthy per third-party route-collector data: bgp.he.net counts 15 valid ROA origins (12 IPv4, 3 IPv6) and zero invalid. That figure comes from a BGP-collector snapshot rather than a direct query of an RIR Trust Anchor, so it should be read as directional rather than a certified compliance statement.

Size

~1.37M IPv4 addresses (~5,356 /24-equivalents) — RIPEstat's canonical announced_space.v4 puts this at 31 prefixes / 1,371,648 addresses, visible to 329 of 330 RIS peers; secondary BGP collectors disagree on the exact live prefix count, likely reflecting differing measurement windows (30 current per bgp.tools vs 34 total origin / 139 route-table entries per bgp.he.net); IPv6: RIPEstat records 3 prefixes announced today (bgp.he.net's all-time view shows up to 23); CAIDA AS rank 1,253 with a customer cone of 27 ASNs / 274 prefixes / 2,120,224 addresses and asnDegree total 38 (customer 21, peer 13, provider 4) [Confirmed for RIPEstat/CAIDA figures; Likely for secondary-collector detail] — https://stat.ripe.net/AS766, https://stat.ripe.net/data/routing-status/data.json?resource=AS766, https://bgp.he.net/AS766, https://bgp.tools/as/766, https://api.asrank.caida.org/v2/restful/asns/766

Analyst note

Encountered as an actively-routed Spanish NREN ASN, not dormant. BGP-collector sources disagree on precise live prefix counts (likely reflecting differing snapshot windows/methodology) but agree on total address space and core upstreams. RIPEstat's own canonical prefix count (31) is used as the authoritative ipv4_prefix_count over the disagreeing secondary collectors. CAIDA ASRank returns rank 1,253 with a customer cone of 27 ASNs / 274 prefixes / 2,120,224 addresses — recorded here rather than left as the bgp.tools ordinal, since CAIDA does return a value for this ASN. The bgp.he.net bogon note is flagged as unconfirmed rather than asserted as fact.
