About this network

NETNET-NET is the internet network of NetNet, part of the Nsight family of companies based in Green Bay, Wisconsin — the same group behind Cellcom and Nsight Telservices.

What it's used for

• Broadband access for homes and businesses across northeastern Wisconsin.
• Regional connectivity for Nsight's wider telecom operations.

Notable

• This is an eyeball network: traffic runs heavily inbound, because the addresses terminate at subscribers pulling content down rather than at servers serving it up.
• The address footprint is substantial for a regional provider, reflecting a customer base spread across a rural and small-city service area rather than a dense metro.

Interesting

• Nsight is one of the relatively few remaining independent, locally owned telecom groups in the Upper Midwest, running both wireline internet and a mobile carrier under one roof.
