Summary

Ministry of Defense of Ukraine

Ukraine · AI-generated

government military defense

The AS handle GM-AS is held by the Ministry of Defense of Ukraine.

What it's used for

  • The address space carries government and military traffic, as indicated by the registrant Ministry of Defense of Ukraine and netname ORG-MODO3-RIPE.
  • The AS announces a single IPv4 prefix, 91.233.103.0/24, comprising 256 addresses, with 0 IPv6 prefixes.
  • With only 2 observed neighbours, the network operates as a small, isolated government estate rather than a transit or access provider.
  • Traffic from this AS consists of internal ministry communications, command and control systems, and administrative endpoints for the Ukrainian military establishment.

Notable

  • The RDAP registrant Ministry of Defense of Ukraine matches the AS holder name exactly.
  • The address inventory is minimal, consisting of a single /24 block, which is typical for a specific government agency rather than a large-scale ISP.

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 1,782 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.
