AS592

Not announced

Operated by DNIC-AS-00592 - Navy Network Information Center (NNIC).

Summary

// analyst note
Dormant legacy DoD/Navy DNIC ASN. Last originated 131.121.0.0/16 and 131.122.0.0/16 between 2000-08 and 2003-02; not currently announced. Zero RIS peer visibility (0/326 v4, 0/322 v6) and CAIDA cone/degree all effectively empty. Allocated_date taken strictly from the RDAP autnum object's top-level events[], excluding decoy entity-level (POC/registrant) event dates.
// security note
NEUTRAL/DATED: no notable public abuse, hijack, or threat-feed signal found for AS592 as of 2026-07-17; checked Spamhaus blocklists, NANOG archives, and BGP-hijack/route-leak searches.

About this ASN.

Updated  ·  Confidence: High

AS592 is a legacy Defense Network Information Center (DNIC) autonomous system registered under ARIN to the Navy Network Information Center (NNIC), a U.S. Department of the Navy organization headquartered in Virginia Beach, VA, with administrative and abuse contact routed through DISA-Columbus in Whitehall, OH. The ARIN RDAP autnum object's top-level registration event dates the allocation to 1990-03-01, with a last-changed timestamp of 2011-07-15; this is a first-party RIR registry fact distinct from the entity-level (registrant/POC) record dates found deeper in the same RDAP response, which reflect unrelated contact-object housekeeping rather than the ASN's own allocation. Operationally, AS592 is dormant: RIPEstat's as-overview flags it as not currently announced, and its routing-status history shows it last originated announcements for 131.121.0.0/16 and 131.122.0.0/16 between August 2000 and February 2003, with no BGP activity observed since. Zero of the 326 IPv4 and zero of the 322 IPv6 RIS peers currently see it, and CAIDA AS Rank places it at 79,459 with a customer cone of a single ASN (itself), zero prefixes, and zero addresses — degree metrics (customer, peer, provider) are all zero. PeeringDB lists AS592 as one of thirteen sibling ASNs under the same NNIC organization record, but the AS592-specific network entry carries no populated peering policy, IRR record, or route-server information. No public abuse, hijack, or threat-feed signal ties to AS592 specifically as of 2026-07-17.
