Summary

Imprensa Nacional-Casa da Moeda

Portugal · AI-generated

government printing business pt

The AS handle IMPRENSANACIONAL-PT-AS is held by Imprensa Nacional-Casa da Moeda, S.A.

What it's used for

  • The address space carries internal corporate traffic for the Portuguese national printing house, as indicated by the netname IMPRENSANACIONAL-PT-NET and registrant Imprensa Nacional-Casa da Moeda, S.A.
  • The inventory consists of 256 IPv4 addresses in a single /24 prefix (193.17.0.0/24) with 0 IPv6 prefixes, observed against 1 routing neighbour, indicating a small, self-contained internal network rather than a transit or access provider.

Notable

  • The registrant Imprensa Nacional-Casa da Moeda, S.A. matches the AS holder, though the RDAP data also lists MEO-EMPRESARIAL and Abuse INCM as associated entities for the prefix.
  • The address inventory is a single contiguous /24 block, consistent with a dedicated corporate estate for a specific government agency.

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.
