What is a private IP address?
A private IP is used inside your local network and is not routable on the internet. Learn the private ranges and find your public IP free.
A private IP address is one reserved for use inside a local network — like 192.168.1.10 — and is not routable on the public internet. Many devices share a single public IP through your router using NAT.
The private ranges
Three blocks are reserved for private use: 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16. Any address in these ranges only has meaning within a local network, which is why the same 192.168.1.1 exists in millions of homes at once. Routers translate between private and public addresses via NAT.
Private vs public
Your device uses a private IP to talk to your router and other local devices; the router presents one public IP to the internet on their behalf. Websites only ever see the public IP — check yours with a What’s-my-IP tool.
