Summary

ACOSS

France · AI-generated

government social-security france

The AS handle CIRTILNET is held by Agence Centrale Des Organismes De Securite Sociale (ACOSS).

What it's used for

  • The address space carries government social security infrastructure, evidenced by netnames cirtilnet, FR-CERTI, and ACOSS with registrants including ACOSS EPA and NOC REZOPOLE.
  • The network announces 768 IPv4 addresses across 3 prefixes with 2 observed neighbours, indicating a small, self-contained internal estate rather than a transit or access provider.
  • Traffic consists of internal administrative and operational systems for the French central agency for social security organizations.

Notable

  • Registrants align with the announcer, listing Agence Centrale Des Organismes De Securite Sociale, ACOSS EPA, and NOC REZOPOLE across the prefixes.
  • The inventory consists of three /24 blocks: 91.209.25.0/24, 193.178.136.0/24, and 194.0.166.0/24.

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 1,781 prefixes, as published 2026-10-16. 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.
