What is my private IP address?
Your private IP address — also called your local IP or LAN address — is the number your router hands out to your device inside your own network. It almost always starts with 192.168., 10., or 172.16 through 172.31. It identifies your laptop or phone to the router, printer, and other devices at home, and it is invisible to the rest of the internet.
The checker below tries to read it in your browser and shows your public IP next to it, so you can see both addresses at once.

Private IP vs public IP
The two addresses do different jobs. Your private IP is local and reusable — millions of homes have a device sitting on 192.168.1.5. Your public IP is the single address your internet provider assigns to your router, and it is the one websites see when you visit them. The router translates between them, which is why every device in your home shares one public address. Check yours on the what is my IP page.
- Private IP: 192.168.x.x, 10.x.x.x, or 172.16–172.31.x.x — assigned by your router, visible only on your network
- Public IP: assigned by your internet provider — visible to every site you open
- Used for: port forwarding, printer and NAS setup, router admin pages, home server access
Why the checker may say unavailable
Browsers can only see the local address through WebRTC, a feature built for video calls. Chrome, Safari, and Firefox now mask or block it by default because advertisers abused it for tracking. If the result above shows unavailable, nothing is broken — your browser is protecting you, and you can read the address directly from your device in a few clicks.
How to find your private IP address on any device
- Windows: open Command Prompt and run
ipconfig. The IPv4 Address under your active Wi-Fi or Ethernet adapter is your private IP. Settings → Network & internet → your connection shows the same value. - macOS: System Settings → Network → select Wi-Fi or Ethernet → Details. The IP address is on the TCP/IP tab. In Terminal,
ipconfig getifaddr en0prints it directly. - iPhone and iPad: Settings → Wi-Fi → tap the (i) next to your network → IP Address.
- Android: Settings → Network & internet (or Connections) → tap your Wi-Fi network → look under advanced details for the IP address.
- Linux: run
ip addrand read theinetvalue on your wlan or eth interface. - Router admin page: most routers list every connected device with its assigned private IP — useful when you need another device's address, not your own.

FAQ
What is my private IP address?
Your private IP address is the address your router assigns to your device inside your own network. It almost always starts with 192.168., 10., or 172.16 through 172.31. This page tries to detect it in your browser, and also shows your public IP for comparison.
What is the difference between a private IP and a public IP?
A private IP identifies your device inside your home or office network and is reused on millions of networks worldwide. A public IP is the single address your internet provider gives your router, and it is what websites see when you connect. Your router translates between the two.
Why does my private IP show as unavailable?
Browsers detect the local address through WebRTC, and Chrome, Safari, and Firefox now hide or mask it by default for privacy. When that happens the checker cannot read it, which is expected. You can still find it in your operating system's network settings in a few clicks.
How do I find my private IP address on Windows?
Open Command Prompt and run ipconfig. The IPv4 Address line under your active Wi-Fi or Ethernet adapter is your private IP. You can also open Settings, then Network & internet, select your connection, and read the IPv4 address.
How do I find my private IP address on a Mac, iPhone, or Android phone?
On a Mac open System Settings, then Network, select your connection and click Details. On an iPhone open Settings, tap Wi-Fi, tap the (i) next to your network, and read IP Address. On Android open Settings, then Network & internet or Connections, tap your Wi-Fi network, and look for the IP address.
Is it safe to share my private IP address?
A private IP such as 192.168.1.42 means nothing outside your own network, so sharing it reveals very little. It cannot be used to reach your device from the internet. Your public IP is the more sensitive one, since it points to your connection.
Does this page store my IP address?
No. The private IP check runs in your browser and is never sent to us. The public IP is looked up by your browser directly from a third-party lookup service and is not stored on our servers.
