Finding an IP address on Windows using the command line is a fundamental skill for troubleshooting network issues, verifying connectivity, or gathering system information. The Command Prompt and PowerShell provide several built-in tools that deliver this information instantly without requiring a graphical interface. This process is straightforward, yet understanding the different commands and their specific outputs ensures you gather the precise data you need, whether it is for your local machine or a remote device.
Understanding Your Network Configuration
Before diving into the commands, it is helpful to understand what IP address you are looking for. A Windows machine typically has multiple addresses: the IPv4 address, which is the most commonly used format, and the IPv6 address, which is gradually becoming the standard. You might also need to distinguish between the local address assigned by your router and the public address assigned by your internet service provider. The command line allows you to view all of these details clearly, layer by layer.
Using the ipconfig Command
The ipconfig command is the primary tool for displaying all current TCP/IP network configuration values. It is the go-to command for most users because it provides a concise overview of your network adapters. Running this command in the Command Prompt or PowerShell will list your Ethernet adapter and Wireless LAN adapter, along with their respective IP addresses.
Executing ipconfig
To use this utility, open the Start menu, type cmd or PowerShell , and press Enter. Once the terminal window appears, type ipconfig and press Enter. The output will immediately populate your screen with details such as the Host Name, Primary DNS Suffix, and Connection-specific DNS Suffix. Locate the section for your active connection—usually labeled "Ethernet adapter" or "Wireless LAN adapter"—and look for the entries labeled "IPv4 Address" or "IP Address."
The ipconfig /all Variation
If the basic ipconfig output does not provide enough context, you can append /all to the command. This switch reveals significantly more information, including the MAC address (Physical Address), DHCP server details, DNS servers, and the status of the network media. This is particularly useful when you are trying to diagnose why a device is not connecting to the network or verifying specific adapter settings.
Finding the Public IP Address
While ipconfig shows your local network address, it does not display your public IP address, which is the identifier used to communicate with the internet. To find this, you must query an external source directly from the command line. You can use PowerShell to send a request to a web service that returns your public IP as plain text, bypassing the need to open a browser.
PowerShell Web Request
To retrieve your public IP, open PowerShell and type the following command: (Invoke-WebRequest -uri "https://api.ipify.org?format=text").Content . Press Enter, and the terminal will display only the IP address. This method is efficient because it does not rely on parsing HTML; it returns the raw text value directly, making it ideal for scripting or quick manual checks.
