ISP finder: home internet without CGNAT near you

How to read this

State comes only from each ISP's own state or city list, or the region we list for small regional ISPs. Satellite and 5G home internet are sold nationwide and show up for every state, but availability depends on your address. 15 ISPs aren't mapped to states yet, so they're hidden when you pick a state. See ISPs by state.
Static IP on home plans is "Yes" when the ISP sells or offers a static IP on residential service (sometimes only on top plans).
Upload is "Symmetrical" when at least some plans upload as fast (or nearly as fast) as they download.
Ports: "Blocked" means the ISP says it blocks or filters inbound traffic on that port. "Not blocked" means the ISP says it doesn't, or the port isn't on its own published blocked-ports list. The terms may still restrict servers, so check the ISP page. Known so far: port 25 for 9 ISPs, port 80 for 8, port 443 for 8.
Behind CGNAT, no inbound IPv4 port works without a public IP, whatever the port status says. Check whether you're behind CGNAT.
