Every device on a local network requires a unique identifier to communicate, and the LAN IP address is that essential label. Understanding how to check this address allows you to troubleshoot connection issues, secure your network, and manage devices effectively. This guide provides clear, step-by-step instructions for finding your local IP address on any common operating system.
Understanding the Difference Between LAN and Public IPs
Before diving into the methods, it is important to distinguish between a LAN IP and a public IP address. The LAN address, typically formatted as 192.168.x.x or 10.0.x.x, is only visible within your private network created by your router. In contrast, your public IP is the address seen by the wider internet, assigned by your Internet Service Provider. Checking the local address is useful for internal troubleshooting, while the public address matters for tasks like remote access setup or verifying port forwarding.
Checking the Address on Windows Systems
The Command Prompt and Settings app provide quick access to network details on Windows machines. The Command Prompt method is often the fastest for experienced users, while the graphical interface offers a more visual approach for those who prefer menus.
Using Command Prompt
Press Win + R , type cmd , and hit Enter.
Type the command ipconfig and press Enter.
Look for the section labeled "Ethernet adapter" or "Wireless LAN adapter."
The value next to "IPv4 Address" is your local LAN IP.
Using Settings App
Open Settings and navigate to Network & Internet.
Click on "Status" and then "View your network properties."
Under "Properties," locate the "IPv4 address" entry.
Checking the Address on macOS
Apple’s macOS offers two primary methods involving the graphical interface and the Terminal application. Both are efficient, but the Terminal provides a direct command-line output that is familiar to IT professionals.
Using System Settings
Open System Preferences (or System Settings) and select "Network."
Select your active connection (Wi-Fi or Ethernet) from the sidebar.
Click the "Advanced" button and navigate to the "TCP/IP" tab.
The "IPv4 Address" field displays your local address.
Using Terminal
Open the Terminal application from Applications > Utilities.
Type the command ifconfig and press Enter.
Look for the interface you are currently using, such as en0 for Wi-Fi.
The value next to "inet" is your LAN IP address.
Checking the Address on Linux
Linux distributions provide flexibility, with multiple commands capable of delivering the same result. The ip command is the modern standard, while older systems might rely on ifconfig .
Open a terminal window.
Type ip addr show and press Enter.
Scan the output for the interface name (e.g., wlan0, eth0).
Locate the "inet" section; the address listed here is your LAN IP.
