On its own,
ipconfig gives a brief readout of the active networking hardware’s local IP address—useful for identifying your PC when looking separately at your router’s list of connected devices.
But the real beauty of ipconfig is when Windows 10’s network troubleshooting isn’t fixing your connection woes and you need to manually release (
ipconfig /release) and renew (
ipconfig /renew) your IP address. You can also see full detailed information of all of your networking hardware, including the MAC address for when you need to add it to a whitelist, whether or not it’s connected (
ipconfig /all).
