Summary

Département de l'Isère

France · AI-generated

government france public-sector

The AS handle ISERE-AS is held by Département de l'Isère.

What it's used for

  • The address space carries government infrastructure, evidenced by netnames FR-CG38CIR03 and FR-CG38CIR06 registered to the Département de l'Isère.
  • The network announces 1536 IPv4 addresses across 3 prefixes with only 1 observed neighbour, indicating a small, isolated internal network rather than a transit or access provider.
  • Traffic from this AS consists of internal administrative and public service endpoints for the French regional government department.

Notable

  • Registrants for the specific /24 prefixes align with the AS holder, identifying the Département de l'Isère as the direct owner of the space.
  • The inventory is finely subdivided into three small blocks, consistent with an internal corporate or government estate segmented by site or function.

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: 454 networks and 1,854 prefixes, as published 2026-11-06. 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.
