AS782

AS782 is a French research-network ASN registered to LORIA (Laboratoire lorrain de recherche en informatique et ses applications) under the sponsorship of GIP RENATER, France's national research and education network, and its current routing behavior is intermittent rather than stable: a single prefix flickered on and off during the most recent observation window, and nothing was announced as of this check.

The registrant of record is RENATER (RIPE org handle ORG-RA8-RIPE), which sponsors the ASN on behalf of LORIA, the CNRS/Université de Lorraine/CentraleSupélec/Inria joint research unit the "FR-LORIA" descriptor actually names. RIPE NCC is the current authoritative registry; ARIN's RDAP redirects to RIPE, consistent with a legacy ASN from the original 1–1876 IANA block that transferred region.

RIPE RDAP records a top-level registration event of 2002-08-21 and a last-changed event of 2022-09-15. RIR registry status is "Active," but live routing tells a thinner story: CAIDA marks the AS as not currently seen in its topology graph (rank 79,459, degree 0, customer cone a singleton with 0 prefixes and 0 addresses), and RIPEstat shows 0 observed BGP neighbours. The historical prefix 152.81.0.0/16 was seen announced on only two days (2026-07-27 and 2026-07-29) inside an otherwise-empty two-week window, with 0/328 RIS peers seeing any v4 space and 0 IPv6 space at the time of this check.

Registered IRR policy (RENATER-MNT) lists AS2200 (Renater's main network, preference 100) as default upstream and AS781 (Renater, preference 20) as a secondary — but this is unconfirmed policy metadata, not observed live adjacency, since no BGP neighbours are currently visible from any source. AS782 has no PeeringDB record of its own.

Operator

registrant of record is GIP RENATER (France's NREN); the named network is LORIA, a CNRS/Université de Lorraine/CentraleSupélec/Inria research unit (UMR 7503) [Confirmed] — rdap.db.ripe.net/autnum/782, rdap.db.ripe.net/entity/ORG-RA8-RIPE

Country / RIR

FR, RIPE NCC (ARIN RDAP for autnum 782 redirects to RIPE) [Confirmed] — rdap.arin.net/registry/autnum/782, rdap.db.ripe.net/autnum/782

Allocated

2002-08-21 (RIPE RDAP autnum top-level "registration" event); last changed 2022-09-15 [Confirmed] — rdap.db.ripe.net/autnum/782

Org status

RIR registry status "Active" (RIPE RDAP); operationally quiet — CAIDA seen=false, degree 0, 0 observed neighbours [Confirmed for registry status; Likely for operational-dormancy characterization] — rdap.db.ripe.net/autnum/782, api.asrank.caida.org/v2/restful/asns/782

Contacts

certsvp@renater.fr (abuse, RIPE handle RA6839-RIPE); security-ripe@inria.fr also listed on RDAP entities; GIP RENATER, 23-25 rue Daviel, 75013 Paris, France [Confirmed] — stat.ripe.net/data/abuse-contact-finder, rdap.db.ripe.net/autnum/782

Security/abuse context (NEUTRAL, DATED)

no notable public abuse signal found as of 2026-08-01 — Spamhaus ASN drilldown blocked automated fetch, no AbuseIPDB record, no NANOG archive hits; sourced null finding, not a clean-record claim

Network & routing

Network type

academic/research end-site ASN, client of RENATER's national R&E network umbrella; not an independent commercial or transit network [Confirmed] — rdap.db.ripe.net/autnum/782, loria.fr/en/loria

Size

intermittent — 152.81.0.0/16 observed announced only 2 of 14 days in the most recent RIPEstat window; 0 v4/v6 prefixes announced and CAIDA seen=false as of this check; customer cone = 1 ASN (itself), 0 prefixes, 0 addresses

[Confirmed] — stat.ripe.net routing-status/announced-prefixes, api.asrank.caida.org/v2/restful/asns/782

Routing/peering

no PeeringDB record for AS782 itself; IRR policy (RENATER-MNT) registers AS2200 (pref 100, default) and AS781 (pref 20) as upstreams, but 0 live BGP neighbours are currently observed from any source [Likely — IRR policy metadata, not confirmed live adjacency] — bgp.he.net/irr/as-set/AS-RENATER, stat.ripe.net/data/routing-status

RPKI

not assessable — AS782 announces no prefixes at check time (0 v4/0 v6, 0 observed neighbours), so there is no live route to validate against a ROA [Confirmed] — stat.ripe.net/data/routing-status/data.json?resource=782, stat.ripe.net/data/as-overview/data.json?resource=782

Notable usage

historically announced 152.81.0.0/16 for LORIA-INRIA; currently intermittent/flapping rather than a stable advertisement [Likely] — bgp.he.net/AS782, stat.ripe.net/data/announced-prefixes

Related ASNs

AS2200 and AS781 (Renater, per registered IRR policy) [Likely]; RENATER also operates AS1307 and AS1715 per third-party network summaries [Likely, single source] — bgp.he.net/irr/as-set/AS-RENATER, peeringdb.com/asn/2200

Analyst note

two-layer identity — RENATER is the registrant/LIR, LORIA is the network the "FR-LORIA" descriptor actually names. RIR status is Active but current routing is intermittent, not stable; treat prefix/address counts as a snapshot, not a fixed footprint.
