Summary

Tietokeskus Finland Oy

Finland · AI-generated

business it-services corporate

The AS handle TIETOKESKUS-AS is held by Tietokeskus Finland Oy.

What it's used for

  • The address space carries corporate IT infrastructure, with reverse DNS entries pointing to customers.tamico.com and netnames FI-TIETOKESKUS-20110321 and FI-TIETOKESKUS-20170725.
  • The network announces 3072 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with only 2 observed neighbours, indicating a small, self-contained corporate estate rather than a transit or access provider.
  • Traffic from this AS consists of internal corporate communications and IT service endpoints for Tietokeskus, a Finnish IT service company providing infrastructure solutions to corporate and municipal sectors.

Notable

  • Registrants for both announced prefixes are Tietokeskus Finland Oy, matching the AS holder.
  • Tietokeskus Finland Oy has merged with Enfo to form Aurilo, operating under both the Tietokeskus and Enfo brands.
  • The inventory consists of two distinct IPv4 blocks and one IPv6 block, reflecting a segmented internal corporate 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: 445 networks and 1,817 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.
