Summary
Commando Materieel en IT
government enterprise infrastructure
Fifty-two neighbours for five thousand addresses, which is not how a government network usually connects.
What it's used for
- A state materiel and information technology command. Two IPv4 prefixes and one IPv6
/36announced from the Netherlands, five thousand addresses, across fifty-two observed BGP neighbours.
Notable
- The two IPv4 blocks are a
/20and a/22from unrelated parts of the address space, with allocation dates in their netnames eighteen years apart. - The AS handle carries a town name and the country, which is more geography than these fields normally hold.
- Both blocks list the same two registrants: a management role for registry work, and the command itself.
- The IPv6 prefix is far larger than the IPv4 holding, which is normal, since address scarcity does not apply on that side.
- Six addresses were queried for reverse DNS and none returned a name.
Interesting
- Fifty-two neighbours is the number that stands out. That is more interconnection than most networks ten times this size carry, and it means traffic reaches here by many independent paths.
- An eighteen-year gap between allocations says the original block sufficed for most of the network's life, and something changed recently enough to need more.
- Nothing published in reverse across five thousand addresses is a defensible choice for an organisation that would rather not have its internal structure read out of DNS.

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 1,783 prefixes, as published 2026-10-20. 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.
