ipconfig

IP Configuration Utility

What Does It Do?

The ipconfig command shows your computer's IP address and network settings. Think of it like checking your home address and phone number for your computer on the network.

It displays important information like your IP address, subnet mask, default gateway (your router), and DNS servers. This is usually the first command you run when troubleshooting network problems.
