About this network

ASN-NO-STERIA is operated by Sopra Steria AS.

What it's used for

• The address space carries corporate IT infrastructure for a major European consulting and digital services firm, with netnames including NO-STERIA-NORWAY-20140221, NO-STERIA, and NO-DGI.
• The AS announces 4096 IPv4 addresses across 6 prefixes and 21 IPv6 prefixes, while maintaining only 2 observed routing neighbours, indicating a small, self-contained corporate network rather than a transit or access provider.
• Traffic from this AS consists of office workers, consultants, and internal IT endpoints supporting the company's digital transformation services across its Norwegian offices.

Notable

• Registrants largely align with the announcer, with SOPRA STERIA AS listed for most prefixes, though Utlendingsdirektoret and Digitale Gardermoen IS appear as registrants for specific blocks, suggesting leased or historically allocated space.
• The address inventory is finely subdivided into multiple /22, /23, and /24 blocks, consistent with internal corporate segmentation for different sites or departments.
• Sopra Steria was formed in 2014 through the merger of French IT services companies Sopra and Steria.
