Summary

Stadtverwaltung der Stadt Bern

Switzerland · AI-generated

government municipal switzerland

BERN is operated by Stadtverwaltung der Stadt Bern, the municipal administration of the city of Bern.

What it's used for

  • The address space carries the city's internal IT infrastructure, as indicated by the netname ADV-BERN-BLOCK2 and registrant Informatik Stadt Bern.
  • The AS announces 1024 IPv4 addresses in a single /22 prefix and one IPv6 /48 prefix, with only 2 observed routing neighbours, indicating a small, self-contained corporate estate rather than a transit or access network.
  • Traffic from this AS consists of municipal government services, administrative endpoints, and internal network infrastructure for the city of Bern.

Notable

  • The registrant Informatik Stadt Bern aligns directly with the AS holder Stadtverwaltung der Stadt Bern, confirming the space is owned and operated by the city's IT department.
  • The inventory is compact and finely subdivided, consisting of a single IPv4 block and a single IPv6 prefix, typical of a municipal internal network.

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 1,782 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.
