Summary

Cyber Test Systems

France · AI-generated

business testing france

The AS handle CTS-AS is held by Cyber Test Systems SAS.

What it's used for

  • The address space carries corporate infrastructure, evidenced by the netname FR-CYBER-TEST-20190125 and registrants including "Cyber Test Systems Administrators" and "Cyber Test Systems Technicians".
  • The network announces 1024 IPv4 addresses within a single /22 prefix and one IPv6 prefix, with only one observed neighbour, indicating a small, self-contained corporate estate rather than a transit or access provider.
  • Traffic from this AS consists of internal corporate operations for a company specializing in software and system testing services.

Notable

  • Registrants align with the announcer, listing specific administrative and technical roles within Cyber Test Systems SAS.
  • The address inventory is compact, consisting of a single contiguous IPv4 block and a single IPv6 prefix, typical of a dedicated corporate network.

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: 452 networks and 1,853 prefixes, as published 2026-11-05. 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.
