AS484

AS484 is a dormant, unannounced autonomous system number that falls within a contiguous ARIN block registration named AFCONC-BLOCK1-AS, spanning AS379 through AS508 and held by the registrant organization "Air Force Systems Networking" (ARIN org handle 7ESG). Because ARIN registers this range as a single block rather than issuing AS484 its own standalone delegation, RDAP queries for AS484 resolve to the block's top-level record, handle AS379. The block's top-level registration event dates to 1989-08-04, with a last-changed event on 2008-06-06; these are first-party ARIN RDAP facts recorded at the autnum's top level, not third-party database artifacts. The registrant is administered by DISA Columbus (754th Electronic Systems Group) out of Gunter Annex, Maxwell AFB, Alabama, and the block underpins USAF/DoD network infrastructure, including AFNET, the Air Force's unclassified network, run over DISA-provisioned DISN transport. Every routing dataset checked — RIPEstat, CAIDA AS Rank, and bgp.he.net — agrees AS484 has never announced an IPv4 or IPv6 prefix and carries zero BGP peers or upstreams, consistent with a closed government block-reservation ASN rather than a routed commercial network. No public abuse signal was found: AS484 does not appear in Spamhaus ASN-DROP, and unlike its already-enriched sibling AS470 (which carries a historical pre-2012 bogon note), bgp.he.net shows no flags at all on AS484's page.

Operator website / peering policy

Unknown — no operator-specific website or PeeringDB network object was verified for AS484 or the AFCONC-BLOCK1-AS registrant; a similarly-named PeeringDB org exists but lists a non-overlapping ASN set [Unknown] — https://www.peeringdb.com/org/20118

Security/abuse context (NEUTRAL, DATED)

no notable public abuse signal found as of 2026-07-10 — not present in Spamhaus ASN-DROP (verified via live JSON dataset); bgp.he.net/AS484 shows no bogon, hijack, or route-leak annotation (unlike sibling AS470, which carries a historical pre-2012 bogon note); no AS484-specific NANOG archive discussion found

Network & routing

Network type

US Department of Defense / US Air Force government network block (not commercial); supports AFNET, the Air Force's unclassified network, over DISA-provisioned DISN transport [Likely] — https://www.dafcio.af.mil/Portals/64/DAF%20Network%20of%20the%20Future%20Strategy_vF.pdf

Size

dormant — 0 IPv4 prefixes/addresses and 0 IPv6 prefixes; customer cone = 1 ASN (itself), 0 prefixes, 0 addresses [Confirmed] — https://asrank.caida.org/asns/484, RIPEstat routing-status

Routing/peering

NOT announced — 0/326 RIS peers seeing v4, 0/321 seeing v6; CAIDA degree total 0 (customer 0, peer 0, provider 0); no upstreams or peers observed in any source [Confirmed] — https://stat.ripe.net/AS484, https://bgp.he.net/AS484, https://asrank.caida.org/asns/484

RPKI

not assessable — AS484 announces no prefixes, so rpki-validation was skipped (no ROAs to check) [Unknown] — RIPEstat rpki-validation (skipped, no prefix supplied)

Notable usage

part of the AFCONC-BLOCK1-AS block (AS379–AS508) used for Air Force/DoD combat information systems and networks; no standalone public documentation names AS484 specifically [Likely] — https://www.afcea.org/content/air-force-refocuses-network-defense

Related ASNs

part of the AS379–AS508 AFCONC-BLOCK1-AS block; sibling AS470 already enriched under the same registrant [Confirmed] — https://rdap.arin.net/registry/autnum/484

Analyst note

AS484 has no standalone ARIN record; it is a member of a large legacy DoD block registration (AS379–AS508). Registration data is first-party and Confirmed; operational/purpose context is Likely (military-network inference); no public routing or abuse presence found.
