Summary
Finanzdirektion des Kantons Bern
government enterprise infrastructure
Four fifths of the addresses here sit in a /16 registered to a telephone company.
What it's used for
- A cantonal finance authority's network. Seven IPv4 prefixes and one IPv6
/32announced from Switzerland, eighty-one thousand addresses, through two observed BGP neighbours.
Notable
- The largest announcement is a
/16whose registry entry names a carrier and that carrier's own address registry team, not the authority announcing it. - The other five documented blocks share one identical netname, which ends in a two-digit number that matches none of them.
- One block's registry lookup failed, so its details are unknown rather than absent.
- Two neighbours carry eighty-one thousand addresses, which is a narrow connection for that much space.
- Eighteen addresses were queried for reverse DNS and none returned a name.
Interesting
- A carrier's block announced by a government AS is the ordinary shape of an outsourced network. The provider holds the addresses, the customer holds the routing identity, and the registry records only half of that.
- One netname repeated across five blocks of four different sizes means the operator treats them as one pool. The registry has no way to say that, so the netname carries the meaning instead.
- Sixty-five thousand of these addresses come from one grant and the remaining sixteen thousand from six pieces, which is two eras of address policy in one network.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-27, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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.
