AS789

AS789 is an active, currently-announced legacy ASN in the RIPE region, registered to the French research-and-education network operator Renater on behalf of IN2P3, a CNRS particle-physics research institute; it announces three IPv4 prefixes today, all RPKI-valid, and carries no confirmed history of public abuse.

The registry record splits across two entities that should not be collapsed together. Renater (GIP RENATER), the French National Research and Education Network, is the RIR registrant/LIR of record (org handle ORG-RA8-RIPE, Paris). IN2P3 (Institut national de physique nucléaire et de physique des particules), a CNRS research institute, is the AS-name and the presumed operational user — most likely via its computing center CC-IN2P3 in Lyon, though no fetched page explicitly ties CC-IN2P3 to AS789 by number.

Routing is simple and upstream-dependent: AS789 announces 134.158.0.0/16, 193.48.99.0/24, and 193.48.100.0/24 (~66,048 addresses total) with AS2200 (Renater) as sole upstream and default route, plus a direct route-import relationship with AS513 (CERN) — consistent with particle-physics grid computing, though a formal WLCG Tier-1 designation was not confirmed on the fetched IN2P3/CC-IN2P3 pages. There is no PeeringDB record and no published peering policy.

The RDAP autnum's top-level registration event returns 1970-01-01T00:00:00Z, confirmed identically via RIPE RDAP and RIPEstat. This matches RIPE's known epoch-placeholder convention for legacy pre-database ASNs rather than a genuine allocation date, but is recorded here as the literal first-party registry value per project policy; an unverified web summary separately claimed 1993-09-01, which no primary source corroborates. CAIDA ranks AS789 at 13,742 with a singleton customer cone of 3 prefixes.

Operator

dual entity — Renater (GIP RENATER, French NREN, org handle ORG-RA8-RIPE, Paris) is the RIR registrant/LIR; IN2P3 (CNRS particle-physics institute) is the AS-name and presumed operational user, likely via CC-IN2P3 (Lyon)

Country / RIR

France, RIPE NCC [Confirmed] — rdap.db.ripe.net/autnum/789

Allocated

RDAP top-level registration event = 1970-01-01 (recorded as read; this is RIPE's known epoch-placeholder pattern for legacy pre-database ASNs, not a confirmed genuine allocation date — an unverified web claim of 1993-09-01 could not be corroborated) [Confirmed as literal registry value / Unknown as true allocation date]; last changed 2019-06-24

[Confirmed] — rdap.db.ripe.net/autnum/789, stat.ripe.net/data/whois/data.json?resource=AS789

Org status

active (RDAP status); RIPE whois status = LEGACY (pre-current-policy-era allocation, object actively maintained); last modified 2019-06-24 by RENATER operations (rensvp@renater.fr) [Confirmed] — rdap.db.ripe.net/autnum/789

Security/abuse context (NEUTRAL, DATED)

no notable public abuse signal found as of 2026-08-01 — not in Spamhaus ASN-DROP or CleanTalk (0.00% spam rate, 72 monitored IPs); one undated, unresolved "announces bogons" notice on bgp.he.net treated as Unknown significance rather than confirmed abuse; NANOG archive coverage via available search indexes is incomplete so absence of mentions is not conclusive

Network & routing

Network type

legacy (pre-RIR) academic/research ASN; RIPE whois status = LEGACY; functionally part of the French NREN ecosystem, routed via Renater (AS2200) with a direct CERN (AS513) route relationship [Confirmed] — rest.db.ripe.net/ripe/aut-num/AS789.json

Size

3 IPv4 prefixes announced (134.158.0.0/16, 193.48.99.0/24, 193.48.100.0/24), ~66,048 IPv4 addresses; 0 IPv6 prefixes; CAIDA AS rank 13,742; customer cone = 1 ASN, 3 prefixes, 66,048 addresses [Confirmed] — bgp.he.net/AS789, asrank.caida.org/asns/789

Routing/peering

sole upstream AS2200 (Renater, default route for all other networks — live adjacency confirmed, CAIDA asnDegree provider=1, observed_neighbours=1); the RIPE aut-num object also registers an import/export policy naming AS513 (CERN), but this is unconfirmed policy metadata, not observed live adjacency — CAIDA asnDegree peer=0, customer=0, and the single observed neighbour is AS2200 [Confirmed for registered policy and for live-adjacency figures]; no PeeringDB network record found (peeringdb.com/asn/789 and the API query both 404) so no published open/selective/restrictive policy exists [Confirmed] — rest.db.ripe.net/ripe/aut-num/AS789.json, bgp.he.net/AS789, peeringdb.com/asn/789, stat.ripe.net/data/routing-status/data.json?resource=789, api.asrank.caida.org/v2/restful/asns/789

RPKI

3/3 announced IPv4 prefixes RPKI-valid, 0 invalid [Confirmed] — bgp.he.net/AS789, bgp.tools/as/789

Notable usage

IN2P3/CNRS operates CC-IN2P3 (Centre de Calcul de l'IN2P3/CNRS, Lyon) — roughly 52,000 parallel-processing cores and 340 PB storage supporting ~80 experiments including Euclid and Belle II; the direct CERN (AS513) route relationship is consistent with particle-physics grid computing, though a formal WLCG Tier-1 designation was not confirmed on the fetched in2p3.cnrs.fr / cc.in2p3.fr pages

[Likely] — cc.in2p3.fr, rest.db.ripe.net/ripe/aut-num/AS789.json

Related ASNs

AS2200 (Renater, sole upstream); AS513 (CERN, direct route-import peer) [Confirmed] — rest.db.ripe.net/ripe/aut-num/AS789.json

Analyst note

registry record splits registrant (Renater) from AS-name entity (IN2P3); no primary source ties CC-IN2P3 to AS789 by number, so the operational-user link is Likely, not Confirmed. allocated_date is the literal RDAP top-level registration event, flagged as a probable epoch-placeholder artifact rather than a genuine 1970 date.
