Summary

Groupe Lacour

France · AI-generated

business software france

LACOUR is operated by Groupe Lacour (Lacour Concept SAS).

What it's used for

  • The space carries corporate infrastructure for a French software company, identified by the netname GROUPE-LACOUR and registrant Lacour Concept SAS.
  • The AS announces a single IPv4 prefix (91.226.214.0/24, 256 addresses) with 2 observed neighbours, indicating a small-scale internal corporate estate rather than an access or transit network.
  • Traffic from this AS consists of office workers and internal web/API endpoints for a software development and publishing firm based in Saint-Doulchard.

Notable

  • Registrants align with the announcer, listing Lacour Concept SAS and Groupe Lacour for the sole announced prefix.
  • The address inventory is minimal, consisting of a single /24 block with no IPv6 prefixes announced.

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: 442 networks and 1,779 prefixes, as published 2026-10-21. 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.
