AS169

AS169 is a legacy United States Department of Defense Autonomous System Number registered with ARIN to Air Force Systems Networking (AFSN), the U.S. Air Force organization that administers Air Force data communications infrastructure under the Air Force Life Cycle Management Center (AFLCMC). The AS name, HANSCOM-NET-AS, ties it to Hanscom Air Force Base in Bedford, Massachusetts — a major Air Force installation for cyber, network, and electronic-systems programs. The registrant org record (ARIN OrgId 7ESG) lists an address at 501 East Moore Drive, Building 884, Room 1100, Gunther Annex, Maxwell AFB, AL, while the administrative, technical, and abuse point of contact is DISA-Columbus (Defense Information Systems Agency) in Whitehall, OH. The key triage point is that AS169 is effectively dormant: it announces zero IPv4 and zero IPv6 prefixes, is seen by none of the ~327 IPv4 / ~323 IPv6 RIS route collectors, and has no observed BGP neighbours as of June 2026. The only routing signal anywhere in the data is a single transient appearance of 144.105.79.0/24 on 2024-05-07 that no RIS peer saw at query time — consistent with a brief internal route leak or test announcement that did not persist. The org registration remains active (last updated 2025-03-13) even though the ASN record itself has not been refreshed since 2009. AFSN operates several other ASNs (e.g., 65, 123, 175, 221, 301) that may carry current traffic. No notable public abuse signal was found as of 2026-06-17; with no routed address space there is effectively no active IP surface.

Security/abuse context (NEUTRAL, DATED)

no notable public abuse signal found as of 2026-06-17; not on Spamhaus DROP/SBL, CleanTalk, or AbuseIPDB indexed excerpts; Scamalytics scores the wider "Air Force Systems Networking" ISP label 0/100 (covers AFSN block, not AS169 alone); no NANOG/Reddit incident threads found; dormant with no routed surface

Network & routing

Network type

US federal government / military internal network infrastructure; legacy ASN named for Hanscom AFB networking [Confirmed] — whois.ipip.net/AS169, bgp.tools/as/169

Size

zero routed space — 0 IPv4 prefixes / 0 addresses, 0 IPv6 prefixes; dormant, not in the global routing table [Confirmed] — bgp.he.net/AS169, bgp.tools/as/169

Routing/peering

not currently routing; 0 BGP peers, 0 upstreams, 0 observed neighbours; visible to 0/327 IPv4 and 0/323 IPv6 RIS peers; only signal a transient 144.105.79.0/24 on 2024-05-07 [Confirmed] — RIPEstat routing-status, bgp.he.net/AS169

RPKI

not assessable — RIPEstat rpki-validation skipped (no announced prefix); HE shows 0 valid / 0 invalid origins, consistent with zero announcements [Confirmed] — bgp.he.net/AS169

Notable usage

originally the network ASN for Hanscom Air Force Base (Bedford, MA), a major USAF cyber/network/electronic-systems installation; AFSN operates other ASNs (65, 123, 175, 221, 301) that may carry current traffic [Likely] — whois.ipip.net/AS169, peeringdb.com/org/20118

PeeringDB

AFSN has org record org/20118 (last updated 2018-06-02) listing ASNs 65, 123, 175, 221, 301 — AS169 is NOT listed there and has no network-level PeeringDB entry; no peering policy published anywhere [Confirmed] — peeringdb.com/org/20118

Related ASNs

AS65, AS123, AS175, AS221, AS301 (other Air Force Systems Networking ASNs per PeeringDB org/20118) [Confirmed for the PeeringDB listing]

Analyst note

Encountered as a dormant USAF/DoD legacy ASN. Registry active under AFSN, administered by DISA-Columbus; no routed prefixes, no peers, no public abuse signal. CAIDA AS-rank / customer-cone could not be computed (CAIDA query timed out and an unannounced AS would not appear regardless).
