About this network

STATE-OF-WISCONSIN-AS1 is operated by the Wisconsin Department of Administration, the agency that runs shared enterprise technology services for Wisconsin state government.

What it's used for

• Statewide government networking: state agencies, offices, and the public services the state runs online. The announced space is large, several legacy /16s totalling a few hundred thousand IPv4 addresses.

Notable

• Government address space. IPs here belong to state agencies and their systems, not to residential subscribers or hosting tenants, which matters when interpreting traffic that appears to come from "Wisconsin".
• A 1993 ARIN registration. State governments that connected in that era often received Class B-sized blocks, which is why the footprint is far larger than a modern allocation of the same purpose would be.

Interesting

• The University of Wisconsin System holds its own separate, similarly large legacy allocation on AS3128, registered in the same 1993 batch.
