Is my IP public?
This page compares your internet-facing public IP with the WAN/Internet IP shown in your router to reveal private NAT, CGNAT, or double-NAT setups.

You can't reliably read this automatically from a browser; paste it from your router admin page.

Enter your router WAN IP to see the verdict.
We'll compare it against your detected public IP and explain whether port forwarding from the internet is possible.
Learn more about public vs private IPs
Public IP
A public IP is globally routable on the internet. It's what remote services need in order to reach your home network directly.
Private IP
Private IP ranges (like 192.168.x.x) are used inside local networks. They cannot be reached directly from the internet.
CGNAT
Carrier-grade NAT (100.64.0.0/10) means your ISP is sharing a public IP among many customers. Port forwarding usually won't work without ISP changes.
Double NAT
Double NAT happens when your router is behind another router or modem. Even with a public WAN IP, inbound connections may stop at the upstream device.
