About this network

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 STATEMINET on three blocks, plus MICHTRANS-NET, MICHTRANS-OUT, DNRNET, MICHCORRC and MICHLSB.
• 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 -NET and 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.
