Summary

Etat de Fribourg

Switzerland · AI-generated

government switzerland state network

CIEF-AS is the autonomous system for the Etat de Fribourg, the cantonal government of Fribourg in Switzerland.

What it's used for

  • The address space is registered under the netnames ETATFR2 and ETATFR, both assigned to the Etat de Fribourg, indicating a dedicated government network.
  • The AS announces 131072 IPv4 addresses across 2 prefixes (155.228.0.0/16 and 156.25.0.0/16) with only 2 observed neighbours, a ratio consistent with an internal corporate or government estate rather than a transit provider.

Notable

  • The registrants for both announced prefixes match the announcer, identified as Etat de Fribourg.
  • The inventory consists of two contiguous /16 blocks, suggesting a finely subdivided internal network structure typical of large institutional operators.

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 1,772 prefixes, as published 2026-10-15. 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.
