How to find your IP address on your computer

• Private (local) IP address: your computer's address inside your home or office network, given out by the router. It usually starts with 192.168., 10. or 172.16. to 172.31. Other devices on the same network use it to reach your computer.
• Public IP address: the address your whole network has on the internet, shared by every device behind the router. It's what websites and servers see. Your internet provider assigns it, and on most home connections it changes now and then.

1. 1

   Step 1: Open Command Prompt

   Click Start, type cmd and press Enter.

2. 2

   Step 2: Run ipconfig

   ipconfig

   Under your Wi-Fi or Ethernet adapter, IPv4 Address is your private IP address and Default Gateway is your router. ipconfig /all adds more, such as the network card's physical (MAC) address.

3. 3

   Step 3: Or look in Settings

   The IPv4 address is also near the bottom of your connection's properties. Open Settings, Network & internet, then Wi-Fi or Ethernet, and your connection.

4. 4

   Step 4: Find your public IP address

   Open What's my IP in a browser on that computer. It shows your public address (IPv4 or IPv6) the way websites see it.

Mac

Open System Settings, Network, choose Wi-Fi or Ethernet, then Details and TCP/IP. Or in Terminal (en0 is usually Wi-Fi):

ipconfig getifaddr en0

Linux

In a terminal, either of these shows your private address; the second also shows which network card has it:

hostname -I
ip -4 addr show

Desktop Linux also shows it under Settings, Network, in the connection's details.

Your router's address is the Default Gateway from ipconfig on Windows, or ip route | grep default on Linux. It's often 192.168.0.1 or 192.168.1.1. Type it into a browser's address bar to open the router's settings, and sign in with the user name and password printed on the router's label, unless you changed them. That's where you'll find port forwarding and the list of connected devices.

• Private IP: connecting between devices on the same network, such as a shared folder (transfer files from one PC to another), a printer or Remote Desktop at home.
• Public IP: reaching your network from outside, for example through a forwarded port. To test one, see how to check if a port is open.
• Both change: give a device a fixed private address with a reservation in the router, and expect the public one to change unless your provider sells a static IP.

To use your PC from somewhere else, you don't need either address with RemoteAccessApp. Each PC shows up by name in your account, and the connection goes out from the PC to our relay, so a changing public address or a router you can't configure doesn't matter.
