AS570

AS570 is a legacy autonomous system number registered under ARIN to Air Force Systems Networking (org handle 7ESG), a U.S. Air Force / Department of the Air Force internal networking unit based at Maxwell AFB's Gunter Annex, Alabama. The ARIN RDAP autnum object's top-level registration event dates the allocation to 1990-01-16, with a top-level last-changed event of 2008-08-18; administrative, technical, and abuse contact duties are handled by DISA-Columbus (Defense Information Systems Agency, Whitehall, Ohio) rather than the registrant itself. Operationally, AS570 is dormant: RIPEstat, bgp.tools, and bgp.he.net independently agree it currently announces zero IPv4 and zero IPv6 prefixes, and bgp.he.net dates its disappearance from the global routing table to 2012-03-01. CAIDA's AS Rank places it at #79,459 with a singleton customer cone (0 prefixes, 0 addresses), and no PeeringDB network record exists for it (a direct lookup returns 404). As a non-commercial federal government ASN, it has no operator-run website, about page, or published peering policy. No notable public abuse signal was found in Spamhaus ASN-DROP or general threat-feed/NANOG-archive searches as of 2026-07-11. One historical anomaly — a stale, bogon-flagged prefix (195.114.122.0/23, registered to an unrelated party) that bgp.he.net once linked to AS570 pre-2012 — is noted as an unverified routing-table artifact, not an incident.

Org status

active per ARIN RDAP autnum status field, despite routing dormancy [Confirmed] — https://rdap.arin.net/registry/autnum/570

IANA reference

blank/Unknown — no applicable IANA RFC reference located [Unknown]

Security/abuse context (NEUTRAL, DATED)

no notable public abuse signal found as of 2026-07-11 — not present in Spamhaus ASN-DROP; no NANOG/threat-feed incident reports naming AS570

Network & routing

Network type

U.S. military / government internal network, non-commercial (part of a larger block of ASNs registered to Air Force Systems Networking) [Likely] — https://rdap.arin.net/registry/autnum/570

Routing status

dormant — 0 IPv4 and 0 IPv6 prefixes currently announced; not visible in the global BGP table since 2012-03-01 [Confirmed] — https://stat.ripe.net/570, https://bgp.tools/as/570, https://bgp.he.net/AS570

Customer cone / rank

CAIDA AS Rank #79,459; cone = 1 ASN (itself), 0 prefixes, 0 addresses [Confirmed] — https://api.asrank.caida.org/v2/restful/asns/570

Peering

no PeeringDB record (peeringdb.com/asn/570 returns 404) [Confirmed]; CAIDA shows 0 peers, while bgp.he.net separately shows 1 historical peer (AS197178) tied to a stale bogon prefix — conflicting sources, presented as a range/caveat rather than resolved

[Likely] — https://www.peeringdb.com/asn/570, https://api.asrank.caida.org/v2/restful/asns/570, https://bgp.he.net/AS570

RPKI

not assessable — no announced prefixes, therefore no ROAs to validate; bgp.he.net reports 0 valid/0 invalid [Confirmed] — https://bgp.he.net/AS570

Analyst note

Encountered as a dormant, legacy federal-government ASN; ARIN registration is clear and first-party, but operator-facing detail (website, peering policy, notable usage) is largely Unknown because AS570 is non-commercial DoD infrastructure with no public-facing presence.
