Summary

S3NS

France · AI-generated

cloud hosting business france

The AS handle S3NS is held by Thales Cloud Securise SAS.

What it's used for

  • The address space carries cloud infrastructure, evidenced by reverse DNS entries such as 177-222-68-0.bc.s3nsusercontent.fr and registrant netnames FR-S3NS-20120711 and FR-S3NS-20081230.
  • The AS announces 11,776 IPv4 addresses across 10 prefixes and 20 IPv6 prefixes, with only 2 observed neighbours, indicating a dedicated hosting or cloud provider network rather than a transit or access network.
  • Traffic from this AS consists of cloud service endpoints and user content delivery, as S3NS operates a French sovereign cloud platform based on Google Cloud technology.

Notable

  • All registrants for the announced prefixes are consistent with the announcer, listing "IT & Network Support; Thales Cloud Securise SAS; Abuse-C Role".
  • The address inventory is finely subdivided into multiple /22 and /23 blocks within the 177.222.64.0/20 and 95.111.128.0/22 ranges, reflecting internal segmentation of the cloud estate.

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: 446 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.
