AS783

AS783 is a dormant legacy autonomous system registered under RIPE NCC to GIP RENATER, France's National Research and Education Network, that currently announces zero IPv4 and zero IPv6 prefixes anywhere in the global routing table.

The RIPE database still holds AS783 as a valid, active resource — status field LEGACY rather than deregistered — but every routing source checked (RIPEstat, CAIDA ASRank, bgp.he.net, bgp.tools) independently agrees it has no observed BGP peers, no upstreams, and no customer cone beyond itself.

The as-name FR-INRIA2 and RDAP remarks trace back to Institut National de Recherche en Informatique et en Automatique (INRIA), the French national computer-science research institute, but the current registrant object and abuse contact are GIP RENATER's, not INRIA's. No PeeringDB record exists for AS783, so no published peering policy could be confirmed.

The ASN's RDAP autnum shows a top-level registration event of 2002-08-21, corroborated by bgp.he.net's independent "Created" field. A conflicting, uncorroborated 1993-09-01 registration date appears on bgp.tools; this discrepancy is recorded here, not resolved, since only the RDAP-sourced date has first-party support.

Operator

GIP RENATER (Groupement d'Intérêt Public RENATER, France's NREN), registrant/maintainer of record; RDAP remarks preserve a historical link to Institut National de Recherche en Informatique et en Automatique (INRIA) via the as-name FR-INRIA2 [Confirmed] — RIPE RDAP autnum 783

Country / RIR

France (FR), RIPE NCC [Confirmed] — RIPE RDAP; CAIDA ASRank country.iso=FR

Allocated

2002-08-21 (RIPE RDAP autnum top-level "registration" event, eventDate 2002-08-21T16:06:19Z), corroborated by bgp.he.net "Created: August 21, 2002"; last changed 2019-06-24. bgp.tools independently shows a conflicting, uncorroborated "Registration Date: September 1, 1993" — noted as an unresolved discrepancy, not adopted [Confirmed for RDAP date; conflict flagged] — RIPE RDAP, bgp.he.net, bgp.tools

Org status

RIPE status LEGACY — valid, registered resource, not deregistered, but operationally dormant; registrant GIP RENATER is an active French public-interest grouping operating the national R&E network; the historically named assignee INRIA is an active French national research institute

[Confirmed] — RIPE RDAP whois

Contacts

certsvp@renater.fr (abuse, RIPE role RA6839-RIPE); rensvp@renater.fr (administrative); registrant address 23-25 Rue Daviel, 75013 Paris, France (GIP RENATER); RDAP remarks also preserve the historical INRIA address, Domaine de Voluceau, Rocquencourt, BP 105, 78153 Le Chesnay CEDEX, France

[Confirmed] — RIPE RDAP autnum 783

Security/abuse context (NEUTRAL, DATED)

no notable public abuse signal found as of 2026-08-01 — not in Spamhaus ASN-DROP; no relevant NANOG-archive threads found; a light-coverage negative result consistent with a currently unrouted ASN

Network & routing

Network type

legacy academic/research-institute ASN under France's NREN (RENATER); RIPE status field = LEGACY; not a commercial ISP/transit network [Confirmed] — RIPE RDAP whois

Size

dormant — 0 IPv4 prefixes / 0 addresses and 0 IPv6 prefixes currently announced; CAIDA customer cone = singleton (1 ASN, 0 prefixes, 0 addresses); CAIDA AS rank 79,459, seen=false [Confirmed] — RIPEstat routing-status/announced-prefixes, CAIDA ASRank, bgp.he.net, bgp.tools (2026-07/08)

Routing/peering

NOT announced — 0/328 IPv4 and 0/322 IPv6 RIS peers see it; CAIDA degree total 0 (customer 0, peer 0, provider 0); no PeeringDB record exists (peeringdb.com/asn/783 returns 404), so no peering policy specific to AS783 could be confirmed [Confirmed] — RIPEstat, CAIDA ASRank, PeeringDB

RPKI

not assessable — AS783 announces no prefixes, so there is no ROA/origin-validation check to run against a specific prefix [Unknown] — noted independently by two research angles

Notable usage

none currently observed — zero originated prefixes and zero BGP peers on both RIPEstat and bgp.he.net as of the 2026-07-18–2026-08-01 window; no evidence of active production traffic [Confirmed] — RIPEstat announced-prefixes, bgp.he.net

Related ASNs

none confirmed specific to AS783; RENATER's own primary operational ASN is AS2200, but no source ties AS783's history or traffic to AS2200 directly [Unknown] — peeringdb.com/asn/2200, bgp.tools/as-set/as-renater

Analyst note

Dormant/unrouted legacy ASN whose RIPE registrant-of-record is RENATER (France's NREN); RDAP remarks preserve an older INRIA assignee reference. All four routing sources agree on zero current announcements, zero peers, and a singleton customer cone.
