AS76

AS76 is a legacy allocation registered under ARIN to Unisys Corporation, carrying the handle "SDC-CAM-AS." The handle traces to System Development Corporation (SDC), an early software and defense-computing firm — "CAM" referencing its Camarillo/Santa Monica site — which was absorbed into Burroughs and then Unisys; RFC 1020 (1987) lists network 192.5.165 as "SDC-CAM-1." The sibling AS67 (SDC-PRC-AS) is likewise held by Unisys, so the current registry holder is Unisys Corporation, not SDC. The ASN is dormant: it originates zero prefixes and shows no peers, upstreams, or downstreams as of June 2026; Unisys routes production traffic via other ASNs (AS6072, AS15009, AS67). The ARIN ASN RegDate is 1986-05-05; some third-party mirrors (IPinfo) display a 0000-00-00 placeholder, which is not a real date. The historical SDC-CAM-1 block (192.5.165.0/24) could not be confirmed as currently announced by AS76, and since AS76 originates nothing it should be treated as not announced by AS76. For triage this is a vestigial legacy corporate allocation; treat as non-routing. No notable public abuse signal was found as of June 2026.

Analyst note

A vestigial legacy corporate allocation; treat as non-routing. Holder is the corporate successor to SDC (via Burroughs → Unisys), and live Unisys routing is on AS6072/AS15009/AS67.
