Summary

Stelmet S.A.

Poland · AI-generated

business manufacturing corporate poland

The AS handle STELMET-SA is held by Stelmet S.A., a Polish wood product manufacturer.

What it's used for

  • The address space carries corporate infrastructure, evidenced by the netname STELMET-NET and the reverse DNS record sp.stelmet.com.
  • The network announces 256 IPv4 addresses within a single /24 prefix (91.217.132.0/24) and maintains 2 observed routing neighbours, indicating a small, self-contained corporate estate rather than a transit or access provider.
  • Traffic from this AS consists of internal corporate communications and web endpoints for the company's operations in Zielona Gora, supporting its business in sawmills and wood preservation.

Notable

  • The RDAP registrant Stelmet S.A. matches the AS holder, confirming direct ownership of the address space.
  • The inventory consists of a single contiguous /24 block, typical for a mid-sized enterprise managing its own IP resources without complex subdivision.

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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
