Summary

Sopra Steria

France · AI-generated

business infrastructure it-services france

SOPRA-STERIA-ASN is held by Sopra Steria Infrastructure & Security Services SAS.

What it's used for

  • The address space carries internal corporate infrastructure, evidenced by netnames such as FR-SOPRASTERIA-I2S-20190612, FR-SOPRA-HR-OUTSOURCING, and FR-STERIA.
  • The AS announces 2048 IPv4 addresses across 5 prefixes with only 2 observed neighbours, indicating a small, self-contained corporate estate rather than a transit or access network.
  • Traffic from this AS consists of office workers, IT service delivery endpoints, and internal application servers supporting Sopra Steria's global IT consulting and infrastructure management operations.

Notable

  • Registrants align with the announcer, including SOPRA STERIA INFRASTRUCTURE & SECURITY SERVICES SAS, SOPRA HR Software SAS, and SOPRA STERIA GROUP SA.
  • One prefix, 193.240.114.0/24, lists LEVEL 3 COMMUNICATIONS - ABUSE as the registrant, reflecting historical allocation prior to the current ownership structure.
  • The inventory is finely subdivided into five distinct /24 and /22 blocks, consistent with site-by-site segmentation for a large multinational corporation.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-27, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 447 networks and 1,852 prefixes, as published 2026-10-27. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
