AS162

AS162 is a very-low-number, legacy Autonomous System Number registered through ARIN to the Navy Network Information Center (NNIC), a US Navy element administered under the Defense Information Systems Agency (DISA). Its ARIN handle is DNIC-AS-00162 — the "DNIC" prefix marks it as part of the Department of Defense's historic Data Network Identification Code block — and the AS162 record carries a registration event of 1988-03-01, placing it among the earliest autonomous systems ever assigned. The registrant org record (NNICN-1) lists 2465 Guadalcanal Road, Building 1265, Virginia Beach, VA 23459, while administrative and abuse contact routes to DISA Columbus (300 North James Road, Whitehall, OH 43213) via disa.columbus.ns.mbx.arin-registrations@mail.mil. The key triage point is that the registry record is active but the ASN is operationally dormant: as of June 2026 it announces zero IPv4 and zero IPv6 prefixes and is not present in the global routing table. RIPEstat shows 0 of 327 IPv4 RIS peers and 0 of 320 IPv6 RIS peers seeing it; CAIDA reports rank 79459 with a customer cone of just itself, zero AS-degree, no IXP presence, and no clique membership. With no announced address space there is no observable RPKI posture and no attack surface — consistent with the absence of any abuse-feed listing, blocklist entry, BGP-hijack record, or NANOG security mention found across the sources checked. NNIC the organisation remains active (org record last updated 2025-03-13) and holds many other DoD ASNs; AS162 itself is best described as a reserved/legacy DoD ASN that is no longer routed in the public DFZ.

Operator

Navy Network Information Center (NNIC), a US Navy / DoD entity administered under DISA (ARIN OrgId NNICN-1, Virginia Beach, VA) [Confirmed] — ARIN RDAP/WHOIS

Country / RIR

US, ARIN [Confirmed] — https://whois.arin.net/rest/asn/AS162

Allocated

ARIN AS162 registration event 1988-03-01 (one of the earliest ASN assignments); AS record last changed 2011-07-05; registrant org NNICN-1 registered 2006-09-21, last updated 2025-03-13 [Confirmed] — https://rdap.arin.net/registry/autnum/162

Org status

active US federal entity (NNIC under DISA); registrant org record NNICN-1 last updated 2025-03-13 — the organisation is active even though AS162 itself is dormant [Confirmed] — https://whois.arin.net/rest/org/NNICN-1

Security/abuse context (NEUTRAL, DATED)

no notable public abuse signal found as of 2026-06-16 — no Spamhaus/AbuseIPDB/CleanTalk/FraudGuard listing, no BGP-hijack record, no NANOG security thread; the null reflects the ASN's dormant routing state (no exposed IPs), not a coverage gap

Network & routing

Network type

US federal military/government network; legacy DoD ASN, currently dormant (announces no prefixes, absent from the global routing table) [Confirmed] — bgp.tools / bgp.he.net

Size

zero announced address space — 0 IPv4 prefixes, 0 IPv6 prefixes, 0 IPs; CAIDA customer cone = 1 ASN / 0 prefixes / 0 addresses [Confirmed] — bgp.he.net / RIPEstat / CAIDA (2026-06)

Routing/peering

not announced; 0/327 IPv4 RIS peers and 0/320 IPv6 RIS peers seeing it; 0 observed BGP neighbours; no upstreams, peers, or customers; no IXP presence (CAIDA ixp=null); RPKI posture Unknown (no prefixes announced, so no ROAs observable)

[Confirmed for the null routing state] — RIPEstat / bgp.he.net / bgp.tools

Notable usage

legacy DoD/USN ASN (handle DNIC-AS-00162) registered 1988-03-01; NNIC operates many other DoD autonomous systems, but AS162 specifically carries no active address space [Confirmed] — https://whois.arin.net/rest/asn/AS162

Related ASNs

NNIC holds numerous other DoD ASNs (e.g., AS22, AS37, AS48, AS84, AS89, AS139, AS141, AS148) [Likely] — ipinfo.io / networksdb.io

Analyst note

Encountered as a dormant legacy DoD ASN; WHOIS resolves to NNIC under DISA. Registry-active but unrouted; the sourced abuse/routing nulls are honest data, not gaps.
