Summary

voestalpine Tubulars

Austria · AI-generated

business manufacturing corporate steel

The AS handle VAK-AT-AS is held by voestalpine Tubulars GmbH & Co KG.

What it's used for

  • The address space carries corporate infrastructure for a steel manufacturer, as indicated by the netname VAK-AT-NET and the registrant voestalpine Tubulars GmbH & Co KG.
  • The AS announces 256 IPv4 addresses within a single /24 prefix (193.189.136.0/24) and maintains 2 observed neighbours, a ratio consistent with a small internal corporate network rather than a transit or access provider.

Notable

  • The RDAP registrant voestalpine Tubulars GmbH & Co KG matches the registry holder and the AS name, confirming direct ownership of the address space.
  • The address inventory consists of a single contiguous /24 block, typical of a dedicated corporate allocation for site connectivity and internal systems.

Reputation

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 1,779 prefixes, as published 2026-10-23. 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.
