AS682

AS682 (AS-ORNL-IGRP1-AS) is a registered but dormant autonomous system held by Oak Ridge National Laboratory (ORNL), a U.S. Department of Energy national laboratory in Oak Ridge, Tennessee. ARIN's registry status shows it as active, but RIPEstat and CAIDA agree the ASN currently announces zero IPv4 and zero IPv6 prefixes, with none of roughly 325 RIS peers seeing a route to it.

The ASN was registered on 1990-06-13 per ARIN RDAP's top-level autnum event, and last modified 2025-09-24. Registrant contact runs through the ORNL NetMgr group (netmgr@ornl.gov), listed under the organizational handle ORNL-Z. ORNL itself is a DOE-owned facility operated under contract by UT-Battelle, LLC, a joint venture of the University of Tennessee and Battelle Memorial Institute.

CAIDA AS Rank places AS682 at 79,459 globally, with a customer cone limited to itself: zero downstream prefixes, zero addresses, and zero observed peer or provider relationships. No PeeringDB network record exists for AS682, and no publicly documented peering policy was found on ornl.gov or ut-battelle.org, leaving current interconnection arrangements unconfirmed.

ORNL is DOE's largest national laboratory by budget and staff, and it operates the Oak Ridge Leadership Computing Facility (OLCF), a leading DOE supercomputing center. OLCF publicly documented a 2025 upgrade of its network intrusion-detection capacity to 400 Gbps, evidencing a substantial research-network footprint — though that upgrade was not tied to AS682 by name in available sourcing.

Security/abuse context (NEUTRAL, DATED)

no notable public abuse or threat-feed signal found as of 2026-07-18 via web search of Spamhaus, AbuseIPDB, Talos, and NANOG archives (a search sweep, not a live feed pull); ORNL has disclosed institution-level incidents (2007 phishing, 2011 APT) unrelated to outbound ASN abuse [Likely] — https://www.spamhaus.org/resource-hub/botnet-c-c/networks-hosting-botnet-ccs/, https://www.computerworld.com/article/1453725/oak-ridge-national-lab-shuts-down-internet-email-after-cyberattack-2.html, https://thehackernews.com/2011/04/oak-ridge-national-laboratory-hacked.html

Network & routing

Network type

institutional/research network of a federal laboratory, not a commercial ISP or IXP; no PeeringDB network record exists (peeringdb.com/asn/682 returns 404) [Confirmed] — https://rdap.arin.net/registry/autnum/682, https://www.peeringdb.com/asn/682

Size

dormant — 0 IPv4 and 0 IPv6 prefixes announced; customer cone = 1 ASN (itself only), 0 prefixes, 0 addresses [Confirmed] — RIPEstat routing-status / CAIDA AS Rank (2026-07-18)

Routing/peering

NOT announced — 0 of 325 RIS peers seeing it on v4, 0 of 321 on v6; CAIDA degree total 0 (customer 0, peer 0, provider 0); no upstreams or peers visible in any source [Confirmed]. Peering policy is not publicly documented [Unknown] — https://stat.ripe.net/AS682, https://asrank.caida.org/asns/682

RPKI

not assessable — AS682 announces no prefixes, so there are no ROAs to validate; RIPEstat's rpki-validation check was skipped for lack of an announced prefix [Confirmed] — https://stat.ripe.net/AS682

Notable usage

ORNL is DOE's largest national laboratory by budget and staff and operates the Oak Ridge Leadership Computing Facility (OLCF), a leading DOE supercomputing center; OLCF documented a 2025 upgrade of its network intrusion-detection capacity to 400 Gbps [Confirmed for ORNL/OLCF; not tied to AS682 by name] — https://www.olcf.ornl.gov/2025/08/20/olcf-upgrades-its-network-security-infrastructure/, https://en.wikipedia.org/wiki/Oak_Ridge_National_Laboratory

Analyst note

registered and status-active in ARIN's database since 1990 but not currently announcing any routes; a single bgp.tools search snippet (not fetched) describes it as an "inactive BGP network," corroborating the RIPEstat/CAIDA dormancy finding [Likely, single-source] — https://bgp.tools/as/682
