AS780

AS780 is a dormant legacy autonomous system registered to GIP RENATER, France's national research and education network (NREN) operator, that has announced zero IPv4 and zero IPv6 prefixes and has not been visible in the global routing table since June 16, 2026.

RENATER (Réseau National de Télécommunications pour la Technologie, l'Enseignement et la Recherche) is the public entity that runs France's higher-education and research backbone. RIPE's registry records this ASN under the as-name FR-ARAMIS, status LEGACY, with a top-level registration event dated 2002-08-21 (last changed 2019-06-24).

The ASN was not idle in the recent past: it last originated 68.69.52.0/24 from 2022-06-25 through 2026-06-16, after which RIS peer visibility dropped to zero. CAIDA ranks it 67,700 globally, with a singleton customer cone — just AS780 itself, one historical prefix, 256 addresses.

That last-announced block is itself an open question: 68.69.52.0/24 is ARIN-registered space, not the kind of address block typically held by a European R&E operator, and no lease, transfer, or route-leak explanation was found in the sources checked. bgp.he.net separately labels the block "Paris Junior College" (Texas) and flags it as bogon, but this could not be corroborated against RIPEstat, RIPE routing-security notices, or NANOG archives.

At the organizational level, RENATER's network is described as supporting HL-LHC scientific data transfer, EuroHPC connectivity, and the GRID'5000 testbed — these mentions apply to RENATER generally and are not confirmed as specific to AS780's own announcements. RENATER's actively-routed primary ASN is AS2200 (RIPE RDAP name FR-RENATER, same registrant GIP RENATER as AS780).

not on Spamhaus ASN-DROP as of 2026-07-31; dormant in the global routing table per RIPEstat/ipinfo.io/bgp.he.net; one unverified bogon-flagged historical origination (68.69.52.0/24) not corroborated as an incident [Confirmed for blocklist absence and dormancy; Unknown for the anomaly] — https://www.spamhaus.org/drop/asndrop.json, https://ipinfo.io/AS780, https://bgp.he.net/AS780

Network & routing

Network type

National Research and Education Network (NREN) — France's higher-education/research backbone; legacy/dormant (unannounced since 2026-06-16) [Confirmed] — https://www.renater.fr/reseau/national-et-international/le-reseau-renater/, https://bgp.he.net/AS780

Size

dormant — 0 IPv4/IPv6 prefixes currently announced; CAIDA customer cone reports a singleton (1 ASN, 1 historical prefix, 256 addresses) [Confirmed] — CAIDA ASRank API (asn=780), RIPEstat announced-prefixes (2026-07-18 to 2026-08-01)

Routing/peering

NOT currently announced — last originated 68.69.52.0/24 from 2022-06-25 to 2026-06-16; CAIDA AS rank 67,700; topology degree 1 provider / 0 customer / 0 peer (specific upstream not confirmed — bgp.he.net's cited AS22645/LEARN is geographically implausible and uncorroborated) [Confirmed for dormancy/rank; Unverified for upstream identity] — https://bgp.he.net/AS780, CAIDA ASRank API (asn=780)

RPKI

not assessable — no current announcements, so no ROAs to validate [Unknown] — RIPEstat rpki-validation (no result for bare resource query)

Notable usage

RENATER's network (organization level) is associated with HL-LHC data transfer, EuroHPC connectivity, and the GRID'5000 testbed; not confirmed as AS780-specific [Likely] — https://www.renater.fr/reseau/national-et-international/le-reseau-renater/

Analyst note

AS780 is a dormant/legacy RENATER ASN, not the operator's active infrastructure. Its last announced block (68.69.52.0/24, ARIN-registered space) and a third-party bogon flag against it are an unresolved anomaly, not a confirmed hijack.
