The ranges your router reuses
Private ranges — 10.x.x.x, 172.16.x.x–172.31.x.x, 192.168.x.x — work only inside local networks, so every home on earth can reuse 192.168.1.1 without conflict. Your public IP is the single globally-unique one your ISP gives the router.
NAT: one public face, many devices
Network Address Translation rewrites your devices' private addresses to the router's public one and sorts replies back. That's why port-forwarding exists — and why our checker refuses to probe private hosts.
Find both in 30 seconds
Public: run our IP tool. Private: phone or PC Wi-Fi settings, network details (look for 192.168.x.x or 10.x.x.x). If a tutorial asks for 'your IP' for port forwarding, it means the private one.
FAQ
Why is my IP 192.168.x.x on one screen and different online?
The 192.168 address is your private device address; IP-check sites show your router's public address. Both are correct in context.
Can someone hack me with my private IP?
No — private addresses aren't routable on the internet. Your public IP is the one to be mildly careful with.
