AS13325 STOMI - Michigan State Government
Unclassified ARIN
Summary
State of Michigan
government infrastructure enterprise
The netnames read like a government org chart: transport, natural resources, corrections, legislature.
What it's used for
- The network of a United States state government. 508,160 addresses across nine IPv4 prefixes, three observed BGP neighbours, and no IPv6 announced.
Notable
- The prefixes include a /15, four /16s, a /17 and a /18.
- Netnames are
STATEMINETon three blocks, plusMICHTRANS-NET,MICHTRANS-OUT,DNRNET,MICHCORRCandMICHLSB. - The last of those is registered to the state's legislative service bureau rather than to the government itself.
- One prefix's registry lookup failed, so nothing is known about its registration here.
Interesting
- Half a million addresses is among the largest holdings in this range, and it is not a carrier. A state government of this era received space department by department, and each department's name is still stamped on its block.
- Two labels differ only by suffix, one marked
-NETand one-OUT, which is an internal distinction between an inside network and an outward-facing one preserved in a public registry. Whoever chose those names was documenting a firewall boundary. - The legislature holds its own block under its own registration, separate from the executive departments. Constitutional separation of powers turns out to be visible in address allocation.
- No IPv6 at all across half a million addresses is what happens when scarcity never arrives.

No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-02, 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: 449 networks and 1,846 prefixes, as published 2026-11-03. 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.
