Summary

Sopra Steria Belgium

Belgium · AI-generated

business consulting corporate

SOPRASTERIA is operated by Sopra Steria Belgium SA.

What it's used for

  • The address space carries corporate infrastructure for a major European IT consulting and digital services firm, as indicated by the netname BE-SOPRASTERIA-20160615 and registrant Sopra Steria Belgium SA.
  • The AS announces a single IPv4 prefix, 185.156.56.0/22, comprising 1024 addresses, with 0 IPv6 prefixes.
  • With only 1 observed neighbour, this is a small, self-contained corporate estate rather than a transit or access network, consistent with the internal segmentation of a large enterprise.
  • Traffic from this AS consists of office workers, consultants, and internal systems for Sopra Steria's Belgian operations.

Notable

  • The registrant Sopra Steria Belgium SA matches the AS holder and the netname, confirming consistent ownership.
  • Sopra Steria was formed in 2014 from the merger of Sopra and Steria; the Belgian entity also absorbed former Tobania and Ordina operations in 2023 to form the Sopra Steria Benelux organisation.
  • The inventory consists of a single /22 block, a compact allocation typical of a corporate site or regional office.

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: 449 networks and 1,846 prefixes, as published 2026-11-02. 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.
