Summary

// analyst note
French-cloud multi-tenant IPs; the small prefix count masks a large pooled address space, so many distinct customers share each aggregate /16-/15 — attribute to tenant.

About this ASN.

Updated  ·  Confidence: High

AS12876 is the network of Scaleway, a French cloud/VPS/dedicated provider and one of the leading European alternatives to the hyperscalers, registered under RIPE to SCALEWAY S.A.S. (formerly Online S.A.S.) in Paris. It offers cloud instances, Dedibox dedicated servers, and Elastic Metal, and pioneered ARM-based bare-metal IaaS in 2015. A notable routing quirk: the ASN announces only around 23 IPv4 prefixes and a handful of IPv6 prefixes, because its space is advertised as large aggregates (such as 51.15.0.0/16, 51.158.0.0/15, and 195.154.0.0/16) totaling roughly 504,000 IPv4 addresses — so the low prefix count masks a large pooled address space with many distinct customers sharing each /16–/15. RPKI coverage is clean. The lineage runs from Online.net, founded in 1999 by Xavier Niel, which launched the "Scaleway" bare-metal cloud in 2015 and later rebranded fully; the company is part of the Iliad group (its listed upstream is AS12322 Free), and its data-center unit is being spun out as a standalone company, Opcore. As multi-tenant cloud the standard caveat applies — attribute to the current tenant, not Scaleway — and the network appears in scanning/scraping abuse reports consistent with that pattern.
