Poland · AI-generated

business government printing security

The AS handle WAN-PWPW is held by Polska Wytwornia Papierow Wartosciowych S.A. (PWPW S.A.).

What it's used for

  • The space carries the corporate network of the Polish state security printing works, as indicated by the netname PL-PWPW-20130722 and registrant PWPW S.A. - PU.
  • The AS announces 1024 IPv4 addresses across 1 prefix (185.31.88.0/22) with 2 observed neighbours, a ratio consistent with a small internal corporate estate rather than a transit or access provider.
  • Traffic from this AS consists of internal office and production systems for a state-owned enterprise responsible for printing banknotes and security documents.

Notable

  • The registrant Polska Wytwornia Papierow Wartosciowych S.A. matches the AS holder, confirming the space is owned and operated by the same entity.
  • PWPW S.A. is a sole-shareholder company of the Polish State Treasury, established in 2001, operating in the printing industry with its main office in Warsaw.
  • The address inventory is a single /22 block, representing a compact and self-contained corporate 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: 440 networks and 1,773 prefixes, as published 2026-10-13. 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.
