Summary
NetNet (Nsight)
isp residential eyeball legacy
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.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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: 436 networks and 1,771 prefixes, as published 2026-10-13. 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.
