IP address
An IP address is the number that identifies a device on a network, like a street address for data.
What it means for you
Your router gives each device a private address at home, and you need your router’s address to open its settings. Some smart devices and apps ask for a device’s IP address during setup, which you can find in your router or mesh app.
