AS105

AS105 is a legacy spring-1987 allocation with a name-versus-holder discrepancy: its ASName is "MOT-MCD-AS" (MOT = Motorola, MCD = Motorola Computer Division), but the literal ARIN OrgName remains the legacy "Gould Computer Systems Division" (OrgId GCSD-4, Urbana, IL), with contact data pointing to a Motorola Computer Division (email domain mcd.mot.com) — the registry org name was never updated to "Motorola." The number was originally assigned to Gould Computer Systems Division, the minicomputer/real-time-computing unit whose lineage runs Systems Engineering Laboratories → Gould Electronics (1981) → Encore Computer Corporation (1989), with a UNIX development centre in Urbana-Champaign, IL; the "MOT-MCD" branding reflects a later Motorola Computer Division association attached to the Urbana operation. The precise corporate chain (Gould/Encore vs. Motorola) is muddied in the record and is presented here as historical with lineage uncertainty (hence confidence Medium). The ARIN RDAP RegDate is 1987-04-09 (autnum updated 2010-07-14). It is dormant — 0 IPv4 / 0 IPv6 prefixes. For triage this is a classic "old ASName carrying a defunct company name" case, registered but not announcing — low priority. No notable public abuse signal was found as of June 2026.
