About this network

SI-NERGIE is operated by SI-NERGIE GIE.

What it's used for

• The address space carries corporate infrastructure, evidenced by the netname FR-SI-nerGIE and registrant Areva SA on the 91.198.191.0/24 and 193.57.158.0/24 prefixes.
• The AS announces 2560 IPv4 addresses across 5 prefixes and 1 IPv6 prefix, while maintaining 42 observed neighbours; this ratio of moderate address space against a high neighbour count indicates a transit or interconnection role rather than a pure access network.
• Traffic from this AS consists of internal corporate data and web/API endpoints for the Orano group, as indicated by the PeeringDB website pointing to the Orano CSIRT.

Notable

• Registrants for the 91.198.191.0/24 and 193.57.158.0/24 prefixes list Areva SA, while the AS holder is SI-NERGIE GIE; this reflects the historical rebranding of Areva to Orano, with SI-NERGIE serving as the IT entity.
• The address inventory is subdivided into five distinct IPv4 prefixes, including a /22 and three /23s, suggesting site-by-site segmentation typical of a large corporate estate.
