Summary

City of Turku

Finland · AI-generated

government municipal finland

TURUNKAUPUNKI is operated by City of Turku.

What it's used for

  • The address space carries municipal infrastructure, evidenced by netnames such as TURKU, TURKU-2, TURKU-5, and FI-TURUNKAUPUNKI-20171006.
  • The AS announces 3072 IPv4 addresses across 8 prefixes and 1 IPv6 prefix, with only 1 observed neighbour, indicating a small, self-contained internal network rather than a transit or access provider.
  • Traffic from this AS consists of municipal government services, administrative endpoints, and internal city infrastructure for the City of Turku.

Notable

  • Registrants align with the announcer, listing Turun Kaupunki, City of Turku, and TURUNKAUPUNKI for most prefixes, while one prefix (192.103.110.0/23) is registered to Telia Finland Oyj under the netname FI-SONERA-19910731.
  • The inventory includes a mix of /24s and a /22, with one /23 block retained from a previous Telia Finland registration.

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.
