Summary

Narodowe Archiwum Cyfrowe

Poland · AI-generated

government archives digital

NAC-AS is operated by Narodowe Archiwum Cyfrowe (National Digital Archives of Poland).

What it's used for

  • The address space carries government archival infrastructure, evidenced by the netname NAC-GOV-PL and registrant Polish National Digital Archives administrators.
  • The AS announces 512 IPv4 addresses within a single prefix (91.207.156.0/23) and maintains 3 observed neighbours, indicating a small, self-contained internal network rather than a transit or access provider.
  • Traffic from this AS consists of web endpoints and internal services for Poland's national digital archives, which collect and digitise audiovisual materials.

Notable

  • The RDAP registrant Polish National Digital Archives administrators aligns directly with the AS holder Narodowe Archiwum Cyfrowe.
  • The address inventory is compact, consisting of a single /23 block with no announced IPv6 prefixes.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-22, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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 1,779 prefixes, as published 2026-10-23. 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.
