Summary

Rautaruukki Oyj

Finland · AI-generated

business manufacturing corporate

The AS handle RUUKKI is held by Rautaruukki Oyj.

What it's used for

  • The space carries corporate infrastructure for a Finnish metal-based component manufacturer, with the netname FIRA-STEEL associated with the single announced prefix.
  • The network announces 65536 IPv4 addresses within a single /16 prefix (146.81.0.0/16) and maintains only 1 observed neighbour, indicating a small, self-contained internal corporate estate rather than a transit or access provider.
  • Traffic from this AS consists of office workers, engineering systems, and internal corporate endpoints for the company's manufacturing and construction divisions.

Notable

  • The RDAP registrant for the prefix is listed as unknown, while the registry holder is Rautaruukki Oyj; the netname FIRA-STEEL aligns with the company's steel manufacturing business.
  • Rautaruukki Oyj is a Finnish company headquartered in Helsinki that manufactures and supplies metal-based components and systems to the construction and engineering sectors.
  • The address inventory consists of a single contiguous /16 block, typical of a corporate network segmenting its internal operations.

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.
