Summary

Vaisala Oyj

Finland · AI-generated

business corporate measurement finland

VAISALA is the autonomous system for Vaisala Oyj, a Finnish manufacturer of environmental and industrial measurement instruments.

What it's used for

  • The address space carries internal corporate infrastructure, evidenced by the netnames VAISALA and VAISALA-NET1 and the reverse DNS entry hel-ext-demo.vaisala.com.
  • The AS announces 512 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with only 1 observed neighbour, indicating a small, self-contained corporate network rather than a transit or access provider.
  • Traffic from this AS consists of office workers, engineering staff, and web/API endpoints associated with Vaisala's global operations and product development.

Notable

  • Registrants for both announced prefixes are listed as Vaisala Oyj; Vaisala Group IT, which aligns perfectly with the AS holder.
  • The address inventory is compact, consisting of two /24 blocks and a single /48 IPv6 prefix, typical for a mid-sized enterprise managing its own IP space.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-04, 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: 453 networks and 1,853 prefixes, as published 2026-11-05. 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.
