About this network

SUPRANET-WIS is SupraNet Communications, Inc., an independent internet service provider based in Madison, Wisconsin, serving businesses across southern Wisconsin.

What it's used for

• Fiber and fixed-wireless internet access for business customers in the Madison area, plus colocation and hosting services.
• Bulk internet for multi-dwelling units, so a slice of the space reaches residential apartment users.

Notable

• SupraNet was founded in 1994, the same era its AS number and address space were registered, making this a rare case where a low ASN still sits with the small regional operator that originally took it.
• The footprint is modest (a few dozen /24s), which is typical of a single-metro independent ISP rather than a national carrier.
