Summary

NettiTieto Oy

Finland · AI-generated

business finnish small

The AS handle NTG-AS is held by NettiTieto Oy.

What it's used for

  • The address space carries business traffic, evidenced by the reverse DNS record posti24.fi and netnames FI-NTG-20130121 and NTG98.
  • The network announces 768 IPv4 addresses across 2 prefixes with 1 observed neighbour, indicating a small, self-contained business network rather than a transit or large access provider.

Notable

  • Registrants for both announced prefixes are listed as NettiTieto Oy, consistent with the AS holder.
  • The inventory consists of two contiguous IPv4 blocks: 185.16.96.0/23 and 185.16.98.0/24.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-28, 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: 448 networks and 1,851 prefixes, as published 2026-10-29. 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.
