Summary

Ministerstwo Rozwoju i Technologii

Poland · AI-generated

government poland ministry

The AS handle CISG Centrum Informacji Spoleczno-Gospodarczej is held by Ministerstwo Rozwoju i Technologii.

What it's used for

  • The address space carries government infrastructure, evidenced by the netname MRiT and registrant Ministerstwo Rozwoju i Technologii.
  • The AS announces 65536 IPv4 addresses within a single /16 prefix (158.66.0.0/16) and maintains 2 observed neighbours, indicating a small, self-contained government network rather than a transit or access provider.

Notable

  • The registrant Ministerstwo Rozwoju i Technologii aligns directly with the announced prefix, confirming the space is owned and operated by the Polish Ministry of Development and Technology.
  • The address inventory consists of a single contiguous /16 block, typical for a large national government entity managing its own internal network resources.

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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
