Summary

Centrum Zasobów Cyberprzestrzeni Sił Zbrojnych

Poland · AI-generated

government military cyber infrastructure

MON-AS is operated by Centrum Zasobów Cyberprzestrzeni Sił Zbrojnych (Cyber Space Resources Center of the Armed Forces).

What it's used for

  • The address space carries military cyber infrastructure, evidenced by the netname INTERMON and the reverse DNS record reserved126.army.mil.pl.
  • The AS announces 768 IPv4 addresses across 2 prefixes with 2 observed neighbours, indicating a small, self-contained internal network rather than a transit or access provider.
  • Traffic consists of internal military communications and cyber defense operations managed by the Polish Ministry of National Defence.

Notable

  • Registrants for both prefixes match the AS holder, CENTRUM ZASOBOW CYBERPRZESTRZENI SIL ZBROJNYCH.
  • The address inventory is finely subdivided into two small blocks, consistent with a segmented internal corporate or government estate.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-13, 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: 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.
