Summary

Zaporizhstal Integrated Iron & Steel Works PJSC

Ukraine · AI-generated

business industrial steel corporate

The AS handle ZSTAL-AS is held by Zaporizhstal Integrated Iron & Steel Works PJSC.

What it's used for

  • The address space carries internal corporate traffic for a major steel producer, as indicated by the netname ZSTAL-NET and the registrant identity.
  • The inventory consists of a single IPv4 prefix, 193.17.75.0/24, totaling 256 addresses, with 0 IPv6 prefixes announced.
  • With only 1 observed neighbour, the low address-to-neighbour ratio indicates a small, isolated internal network rather than a transit or access provider.

Notable

  • The RDAP registrant matches the AS holder exactly, confirming direct ownership of the address space.
  • Zaporizhstal is a subsidiary of Metinvest, one of Ukraine's largest industrial groups, operating as a significant steel manufacturing facility in Zaporizhzhia.
  • The address inventory is minimal and finely subdivided, consistent with a single-site corporate estate rather than a distributed service network.

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 2026-11-03. 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.
