AS488

AS488 is a legacy autonomous system number registered under ARIN as part of the AFCONC-BLOCK1-AS block registration, a contiguous range spanning AS379 through AS508 held by "Air Force Systems Networking" (ARIN organization handle 7ESG), an entity tied to U.S. Air Force / Department of Defense network infrastructure at Maxwell AFB, Alabama. Because ARIN's RDAP service keys block-style autnum registrations to the block's lowest member, the top-level RDAP object returned for AS488 carries handle "AS379" and the name "AFCONC-BLOCK1-AS," with a top-level registration event dated 1989-08-04 and a last-changed event dated 2008-06-06 — this is the authoritative allocated_date for the block, not a decoy nested-entity timestamp. AS488 itself shows no current routing activity: RIPEstat and bgp.he.net both confirm zero announced IPv4 and IPv6 prefixes, zero BGP peers, and zero upstreams as of 2026-07-10, and CAIDA's AS Rank places it at 79,459 with a singleton customer cone (1 ASN, 0 prefixes, 0 addresses). RIPEstat's historical routing-status data shows a single brief announcement of 132.51.0.0/16 between 2001-09-26 and 2003-01-16, after which the ASN went dark. No dedicated operator website, PeeringDB net record, or public abuse/incident history specific to AS488 was located; this is consistent with a dormant, internally-used DoD legacy resource rather than a commercial or actively peered network.

Security/abuse context (NEUTRAL, DATED)

no AS488-specific abuse, hijack, spam, or botnet signal found in Spamhaus program pages, general web search, or NANOG archive search as of 2026-07-10; absence-of-evidence, not a confirmed clean record, since the live Spamhaus ASN-DROP feed and commercial abuse-intel services were not directly queried (GreyNoise/AbuseIPDB/Shodan InternetDB excluded per project licensing policy)

Analyst note

community corroboration (NANOG, Reddit, public outage reports) was searched and returned nothing AS488-specific, consistent with a dormant, non-public-facing military ASN [Confirmed] — https://ipinfo.io/AS488
