AS141

AS141 is a legacy U.S. Department of Defense Autonomous System Number registered under ARIN to the Navy Network Information Center (NNIC), the organizational label the Navy historically used for its ARIN-registered numbering resources. The ASN was registered on 1987-12-08, placing it in the early MILNET/ARPANET era of military internetworking, and its ARIN autnum record has not been refreshed since 2011-07-05. The registrant address of record is 2465 Guadalcanal Road, Building 1265, Virginia Beach, VA 23459, while the administrative, technical, and abuse contact is now routed through DISA-Columbus (300 North James Road, Whitehall, OH 43213; disa.columbus.ns.mbx.arin-registrations@mail.mil) — indicating the Defense Information Systems Agency now handles ARIN registrations for NNIC-held resources even though the NNIC organizational label persists in the record. The key operational fact is that AS141 is currently dormant: it announces zero IPv4 and zero IPv6 prefixes, RIPEstat reports it as not announced (announced=false), and it is visible to none of the ~326 RIS IPv4 peers or ~319 IPv6 peers. CAIDA corroborates a customer cone of just the AS itself (1 ASN, 0 prefixes, 0 addresses) and an AS-Rank of 79,459, with zero observed peers, providers, or customers. No notable public abuse signal was found as of June 2026 — no Spamhaus DROP/SBL listing, no PeeringDB record, and no NANOG or community incident on record — which for an unannounced government ASN should be read as absence of evidence rather than a security certification. AS141 is best described as one of many NNIC-held DoD ASNs retained on the books but carrying no current global BGP footprint.

US, ARIN [Confirmed]

Allocated

ARIN ASN registration 1987-12-08 (MILNET-era; per ARIN RDAP — NOT an IEEE/third-party artifact); autnum last changed 2011-07-05 [Confirmed]

Org status

active registrant (NNIC, DoD); ASN dormant with no current BGP activity; record administered by DISA [Likely] — bgp.he.net / ipinfo.io

Security/abuse context (NEUTRAL, DATED)

no notable public abuse signal as of 2026-06-13; not on Spamhaus ASN-DROP/SBL; Scamalytics fraud score 0/100 for the NNIC ISP class; no NANOG/Reddit incidents found — absence of evidence, not a certification — spamhaus.org / scamalytics.com

Network & routing

Network type

U.S. DoD / Navy government military network, legacy and currently dormant (no active originations) [Confirmed]

Size

zero footprint — 0 IPv4 prefixes, 0 IPv6 prefixes, 0 announced addresses; CAIDA customer cone = 1 ASN / 0 prefixes / 0 addresses — stat.ripe.net / bgp.he.net / CAIDA AS-Rank (2026-06)

Routing/peering

not announced (RIPEstat announced=false); 0 of ~326 RIS v4 peers and 0 of ~319 v6 peers see any prefix; CAIDA asnDegree total/peer/provider/customer all 0 [Confirmed]; no PeeringDB record (404) [Confirmed]

RPKI

Unknown — no announced prefixes to evaluate; RIPEstat rpki-validation skipped (requires a specific prefix) [Confirmed null]

Notable usage

one of many NNIC-held DoD ASNs (alongside e.g. AS22, AS37, AS48, AS84); admin/abuse now via DISA-Columbus (disa.columbus.ns.mbx.arin-registrations@mail.mil; +1-844-347-2457 ext.2) — ARIN RDAP / networksdb.io

79,459; clique member: false; IXP membership: Unknown (CAIDA ixp=null) [Confirmed]

Analyst note

Live ARIN RDAP, RIPEstat, CAIDA, and bgp.he.net are fully consistent — dormant US Navy legacy ASN; CAIDA lat/lon 0,0 is a placeholder, not a real coordinate; no dedicated NNIC public website located.
