How to Get a Mac Address From an IP

The Media Access Control (MAC) address is a unique identifier assigned to network interfaces for communications on a network. Every device connected to a network has its own MAC address, including computers, smartphones, and routers.

In this tutorial, we will learn how to retrieve the MAC address from an IP address using various methods.

Method 1: Using Command Prompt (Windows)

If you are using a Windows operating system, you can use the Command Prompt utility to find the MAC address associated with an IP address. Follow these steps:

  1. Open the Command Prompt by pressing the Windows key + R and typing “cmd” in the Run dialog box.
  2. In the Command Prompt window, type “arp -a” and press Enter.
  3. A list of IP addresses and corresponding MAC addresses will be displayed. Locate the IP address you are interested in and note down its corresponding MAC address.

Method 2: Using Terminal (Mac OS / Linux)

For Mac OS or Linux users, you can utilize the Terminal application to retrieve the MAC address from an IP address. Here’s how:

  1. Launch the Terminal application by searching for it in your applications or using Spotlight (Cmd + Space).
  2. In the Terminal window, type “arp -a” and press Enter.
  3. A list of IP addresses and their respective MAC addresses will be displayed. Find the IP address you want and make a note of its associated MAC address.

Method 3: Using Network Scanning Tools

There are also network scanning tools available that can help you retrieve the MAC address from an IP address. These tools provide a more user-friendly interface and additional features. Here are a few popular options:

  • Advanced IP Scanner: This tool allows you to scan your network for connected devices and provides detailed information, including MAC addresses.
  • Nmap: Nmap is a powerful open-source network scanning tool that can be used to discover hosts and retrieve their MAC addresses.
  • Angry IP Scanner: Angry IP Scanner is a lightweight and cross-platform tool that can scan IP addresses and display their corresponding MAC addresses.

Using these tools typically involves installing them on your computer, launching the software, and initiating a scan of your network. Consult the documentation for each tool to learn more about how to use them effectively.


Retrieving the MAC address from an IP address can be useful in various situations, such as troubleshooting network connectivity issues or identifying unauthorized devices on your network. By following the methods outlined in this tutorial, you should now have the knowledge to obtain MAC addresses from IP addresses using command line utilities or specialized network scanning tools.
