Summary

TNNet Oy

Finland · AI-generated

hosting business datacenter residential

TNNET-AS is the autonomous system for TNNet Oy, a Finnish IT infrastructure and data center provider.

What it's used for

  • The address space carries a mix of data center and residential access traffic, evidenced by reverse DNS entries such as xdsl.tnnet.fi, dsl.tnnet.fi, adsl.tnnet.fi, and tietoverkkopalvelut.fi.
  • The network announces 37,888 IPv4 addresses across 5 prefixes and 1 IPv6 prefix, while maintaining only 5 observed routing neighbours, a ratio indicative of a local access and hosting network rather than a transit provider.

Notable

  • All registrants for the announced prefixes are consistent with the announcer, listing TNNet Oy and TNNet Oy Network Administration for netnames like FI-TNNET-20060614 and FI-TNNET-20010126.
  • The address inventory is composed of five distinct IPv4 blocks, including a /18 and a /22, alongside a single /32 IPv6 allocation.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-19, 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: 442 networks and 1,783 prefixes, as published 2026-10-20. 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.
