Summary

// analyst note
RDAP for AS468 is a block-level object (handle AS379, startAutnum 379, endAutnum 508) — ARIN registered AS379–AS508 as one legacy DoD block. The 1989-08-04 top-level registration event is the block's allocation date and is recorded as AS468's allocated_date per the RIR-fact rule (not nulled). Decoy entity-level dates (org 7ESG registered 2008-06-05; POC REGIS10-ARIN registered 2009-06-24) were excluded.

About this ASN.

Updated  ·  Confidence: High

AS468 (AFCONC-BLOCK1-AS) is a legacy autonomous system number registered under ARIN as part of a single contiguous block spanning AS379 through AS508, assigned to the U.S. Air Force's internal networking infrastructure. ARIN's RDAP record lists the registrant as "Air Force Systems Networking," with day-to-day registration administration handled by DISA Columbus under the registrant group handle REGIS10-ARIN, addressed to 300 North James Road, Whitehall, Ohio — a Defense Information Systems Agency facility, not the Air Force unit itself. The underlying organization, per ARIN entity 7ESG, is headquartered at Maxwell Air Force Base–Gunter Annex in Montgomery, Alabama, matching CAIDA's independent geolocation of the ASN to central Alabama (32.41°N, 86.25°W). Routing data shows AS468 is a small, non-transit government stub network: it originates exactly one IPv4 prefix, 199.124.118.0/23 (512 addresses), announces no IPv6 space, and connects to the global routing table through a single upstream, AS27064 (DoD Network Information Center), with zero settlement-free peers and zero downstream customers. CAIDA ranks it 54,406th globally by AS rank, reflecting its minimal footprint. The block-level ARIN registration event dates to August 4, 1989, consistent with sibling ASNs in the same 379–508 range that all carry the identical AFCONC-BLOCK1-AS registrant label. No public abuse signal, hijack incident, or NANOG/community discussion of AS468 was located as of July 2026.

part of the AFCONC-BLOCK1-AS block, AS379–AS508, registered as one contiguous ARIN allocation; sibling ASNs (e.g. AS416, AS486) carry the identical registrant label [Confirmed] — https://whois.ipip.net/AS416, https://whois.ipip.net/AS486
Analyst note
The RDAP object returned for AS468 is a block-level record (handle "AS379", startAutnum 379, endAutnum 508) because ARIN registered the entire 379–508 range as one legacy DoD allocation — expected ARIN behavior for this block, not a lookup error. The 1989-08-04 registration date is therefore the block's allocation date and applies to AS468 as a member of that block; it is recorded as allocated_date per the RIR-fact rule, not nulled as a "database artifact."
