Summary

Acciai Speciali Terni

Italy · AI-generated

business steel industrial corporate

ACCIAI_SPECIALI_TERNI is the autonomous system for Acciai Speciali Terni S.p.A., a major Italian stainless steel manufacturer.

What it's used for

  • The address space carries corporate infrastructure, evidenced by reverse DNS entries pointing to ptr.asttech.it, the internal IT domain for the company.
  • The AS announces a single IPv4 prefix, 91.212.219.0/24, comprising 256 addresses, with 2 observed routing neighbours.
  • Traffic from this AS consists of office workers, industrial control systems, and web/API endpoints for the steel production facility in Terni.

Notable

  • The registrant ACCIAI SPECIALI TERNI S.P.A. matches the AS handle and the netname ACCIAI_SPECIALI_TERNI exactly.
  • The company is currently known as Arvedi AST, part of the Arvedi Group, following its exclusion from the Outokumpu/Inoxum merger and subsequent acquisition.
  • The inventory is a single /24 block, indicating a small, self-contained corporate network rather than a multi-site or transit operation.

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 1,781 prefixes, as published 2026-10-16. 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.
