How to Find Your Computer's IP with Windows
The difference between local IP (ipconfig) and public IP, and when you need each one.
You need your IP address — but first, a clarification: there are two different IPs, and you probably need one in particular.
Local IP (within your network)
Command Prompt:
ipconfig
Look for "IPv4 Address" — this is the one other devices on your same network use to communicate with you (sharing files, a printer).
Public IP (facing the internet)
This is the one the rest of the internet sees — search Google for "what is my ip" and it will show up directly, with no command needed.
The local IP is what you need for tasks around the house (sharing a printer, connecting via Remote Desktop on the same network). The public IP is what matters for anything related to the internet outside your network.
Frequently asked questions
Are my local IP and my public IP the same?
No, they're different. The local IP identifies your machine within your own home network; the public IP is what your entire household shows facing the internet.
Does my IP change over time?
The public one usually does, periodically, unless you've contracted a fixed public IP with your provider. The local one can stay stable if you set a static IP, or change if it depends on DHCP.
