About this ASN.

Updated  ·  Confidence: High

AS58 is a legacy allocation registered under ARIN to Shared Services Canada (SSC), the Canadian federal government's consolidated IT-services department in Ottawa — making it the only non-US registration in this block (country CA, ASN type classified GOVERNMENT). Potaroo's legacy-autnums mirror records the original 1980s holder as "DREA-AS — Defence Research Establishment Atlantic," a Canadian defence research laboratory, so the current holder differs from the original (defence-research) holder, though both are Canadian government. The ARIN ASN RegDate is 1985-12-18 (updated 2017-07-13), with the SSC-299-Z org record indicating a 2017 transfer/refresh into SSC. The ASN is dormant in 2026, announcing 0 IPv4 routes and 0 IPv6 routes. For triage this is a legacy number held by a Canadian federal IT agency but not currently originating routes — treat it as a dormant institutional holding. No notable public abuse signal was found as of June 2026.
