AS482

AS482 is a legacy autonomous system number held within a large ARIN block registration spanning AS379 through AS508, named AFCONC-BLOCK1-AS and registered to "Air Force Systems Networking" — a U.S. Air Force / Department of Defense entity administered through DISA Columbus. The block's top-level RDAP autnum record carries a registration event dated 1989-08-04, which is the authoritative allocation date for AS482 as a member of that block; a last-changed event of 2008-06-06 is also on record. Operationally, AS482 is dormant: every routing source checked — RIPEstat, CAIDA AS Rank, and a direct bgp.he.net fetch — agrees it currently announces zero IPv4 and zero IPv6 prefixes, has zero visible BGP peers, and zero upstreams. RIPEstat's routing-status history shows one brief historical announcement, 132.52.0.0/16, originated from 2001-09-26 to 2001-10-23 and never seen since. CAIDA's topology has never observed the ASN (seen=false, cliqueMember=false), giving it an AS rank of 79,459 — near the bottom of the global ranking. No notable public abuse or threat-intelligence signal was found in Spamhaus ASN-DROP, Talos, or NANOG archives as of 2026-07-10, consistent with an inactive, registry-only DoD resource rather than an operating network with abuse exposure.

Allocated

1989-08-04 (ARIN RDAP autnum top-level registration event for the enclosing block AS379–AS508, AFCONC-BLOCK1-AS — a first-party RIR fact, not an entity/contact-record date); last changed 2008-06-06 [Confirmed] — https://rdap.arin.net/registry/autnum/482

Org status

Security/abuse context (NEUTRAL, DATED)

no notable public abuse signal found as of 2026-07-10 — not in Spamhaus ASN-DROP, Talos-indexed content, or NANOG archives; consistent with a dormant registry-only resource

Network & routing

Network type

legacy ARIN direct allocation to a U.S. military/government entity, part of block AS379–AS508 "AFCONC-BLOCK1-AS" (not ISP/hosting/content) [Confirmed] — https://rdap.arin.net/registry/autnum/482

Size

dormant — 0 IPv4 prefixes / 0 addresses currently routed, 0 IPv6 prefixes; historically originated 132.52.0.0/16 (a /16) from 2001-09-26 to 2001-10-23, not seen since [Confirmed] — https://stat.ripe.net/data/routing-status/data.json?resource=482, https://bgp.he.net/AS482

Routing/peering

NOT announced — 0 RIS peers seeing it (0/326 v4, 0/321 v6); CAIDA degree total 0 (customer 0, peer 0, provider 0); no peering policy published [Confirmed] — https://stat.ripe.net/data/routing-status/data.json?resource=482, https://api.asrank.caida.org/v2/restful/asns/482

RPKI

not assessable — AS482 announces no current prefixes, so there is no ROA to validate against [Unknown, sourced] — https://stat.ripe.net/AS482

Notable usage

none observed today; sole historical record is the 2001 announcement of 132.52.0.0/16 [Confirmed] — https://stat.ripe.net/data/routing-status/data.json?resource=482

Related ASNs

sibling member of the AS379–AS508 "AFCONC-BLOCK1-AS" block (e.g. AS479, already documented in /asn/479/) [Confirmed] — https://rdap.arin.net/registry/autnum/482

Analyst note

Encountered as a dormant legacy DoD-block ASN with no public operator website and zero current BGP activity; RDAP lookup returns the covering block handle AS379 (normal ARIN block-naming behavior for this range, not a fetch error).
