AS222

Not announced

Operated by SMALC-HOSTNET-AS - Air Force Systems Networking.

Summary

// analyst note
Dormant/legacy military ASN — one of the earliest ARIN allocations (1988-08-12). WHOIS resolves to Air Force Systems Networking via DISA-Columbus. All routing sources (RIPEstat, CAIDA, bgp.he.net/bgp.tools, IPinfo) agree on zero announcements, zero peers, zero cone. SMALC expansion (Sacramento vs San Antonio Air Logistics Center) is uncertain.
// security note
NEUTRAL/DATED: no notable public abuse signal found as of 2026-06-19; CleanTalk 0% spam rate, no Spamhaus listing located, no NANOG threads, no community blocklist entries.

About this ASN.

Updated  ·  Confidence: High

AS222 is a legacy autonomous system number registered under ARIN to Air Force Systems Networking (AFSN), a U.S. Air Force / Department of Defense networking program office, with the organization handle 7ESG and registrant address at Gunter Annex, Maxwell AFB, Alabama. The ASN's top-level ARIN registration dates to 1988-08-12, placing it among the earliest autonomous system numbers ever allocated. Its name, SMALC-HOSTNET-AS, preserves two pieces of Air Force history: "SMALC" refers to an Air Logistics Center (read variously as Sacramento or San Antonio in third-party sources) and "HOSTNET" was an early Air Force host-level networking initiative. The key triage point for AS222 is that it is effectively dormant today: every routing source consulted (RIPEstat, CAIDA AS Rank, bgp.he.net/bgp.tools, IPinfo) agrees it announces zero IPv4 and zero IPv6 prefixes, is seen by 0 of 327 RIPEstat RIS peers (v4) and 0 of 324 (v6), and carries a CAIDA AS rank of 79,459 with a singleton customer cone (the ASN itself, 0 prefixes, 0 addresses) and an AS degree of 0 across customer, peer, and provider relationships. RPKI posture cannot be assessed because there are no active originations and therefore no ROAs. The ARIN record was last changed 2008-08-18, and administrative/technical contact routes through DISA-Columbus (Defense Information Systems Agency, Whitehall, OH). No notable public abuse signal was found as of June 2026 — not in Spamhaus listings, CleanTalk (0% spam rate over a single tracked email), NANOG archives, or community blocklist feeds — consistent with a clean, dormant ASN held by a military operator with negligible routing attack surface.

Operator
Air Force Systems Networking (AFSN), a U.S. Air Force / DoD networking program office (ARIN org handle 7ESG, Maxwell AFB-Gunter Annex, AL) [Confirmed] — ARIN RDAP autnum/222
Country / RIR
US, ARIN [Confirmed] — RIPEstat abuse-contact-finder (authoritative_rir: arin)
Allocated
1988-08-12 (ARIN registry date from the autnum top-level events, NOT an IEEE date — IEEE publishes no ASN registration dates); last changed 2008-08-18 [Confirmed] — ARIN RDAP autnum top-level events
Org status
active U.S. Air Force / DoD program office (AFSN) per SAM.gov/GovTribe federal contract opportunities; however AS222 itself is inactive in global routing [Confirmed] — govtribe.com, bgp.he.net/AS222

Security/abuse context (NEUTRAL, DATED)

no notable public abuse signal found as of 2026-06-19 — CleanTalk reports 0% spam rate (1 email tracked, 0 blacklisted); no Spamhaus listing located; no NANOG threads; no community blocklist entries; Spamhaus and AbuseIPDB direct lookups returned 403/404 [Confirmed for CleanTalk/routing; Likely for Spamhaus/AbuseIPDB non-listing] — cleantalk.org/blacklists/asn222, bgp.tools/as/222, ipinfo.io/AS222

Network & routing

Network type
US Government / Military — Department of Defense, United States Air Force data communications networking; AS222 is legacy/inactive [Confirmed] — ARIN RDAP, bgp.he.net/AS222
Size
dormant — 0 IPv4 prefixes / 0 IPv4 addresses and 0 IPv6 prefixes; customer cone = 1 ASN (itself), 0 prefixes, 0 addresses [Confirmed] — RIPEstat routing-status / CAIDA AS Rank (2026-06)
Routing/peering
NOT announced — 0 RIS peers seeing it (0/327 v4, 0/324 v6); CAIDA degree total 0 (customer 0, peer 0, provider 0); no upstreams or peers visible in any source; no PeeringDB network record for AS222 [Confirmed]. No public peering policy is published
[Unknown] — RIPEstat routing-status, CAIDA AS Rank, peeringdb.com/org/20118
RPKI
not assessable — AS222 announces no prefixes, so there are no ROAs to validate; RIPEstat skipped rpki-validation (requires an announced prefix) [Confirmed] — RIPEstat rpki-validation
Notable usage
SMALC-HOSTNET-AS preserves Air Force logistics-center ("SMALC") and early host-networking ("HOSTNET") naming; registered 1988-08-12, among the earliest ASN allocations. The AFSN program office at Maxwell-Gunter remains active per federal contracting records, but the ASN itself has been dormant for years [Confirmed for ASN status; Likely for SMALC expansion — sources disagree (Sacramento vs San Antonio Air Logistics Center)] — ARIN RDAP, bgp.he.net/AS222, govtribe.com AFSN opportunity
Related ASNs
parent DoD org (PeeringDB org/20118) lists other DoD ASNs (e.g. AS65, AS123, AS175, AS221, AS301) but not AS222 [Likely per third-party DB] — peeringdb.com/org/20118
Analyst note
Encountered as a dormant legacy military ASN — one of the earliest ARIN allocations (1988). WHOIS resolves to Air Force Systems Networking via DISA-Columbus; zero announcements across all routing sources. Clean, inactive ASN. SMALC expansion is uncertain (Sacramento vs San Antonio) and tagged accordingly.
