How to Obtain Ethernet Addresses

Ethernet addresses, also known as MAC addresses, are unique identifiers assigned to network interfaces for communication within a network. Obtaining these addresses can be essential for network troubleshooting, security, and management purposes. Here’s a guide on how to obtain Ethernet addresses on various devices and operating systems:

1. Windows:

• Using Command Prompt:
  • Open Command Prompt.
  • Type ipconfig /all and press Enter.
  • Look for the “Physical Address” under the Ethernet adapter section. This address is your Ethernet (MAC) address.
• Through Network Settings:
  • Go to Settings > Network & Internet.
  • Select Ethernet on the left sidebar.
  • Click on the network connection.
  • Under Properties, you can find the Ethernet address.

2. macOS:

• System Preferences:
  • Go to the Apple menu > System Preferences.
  • Select Network.
  • Choose Ethernet from the sidebar.
  • The Ethernet address is listed as the “Ethernet ID.”
• Terminal Command:
  • Open Terminal.
  • Type ifconfig en0 | grep ether and press Enter.
  • The Ethernet address is displayed next to “ether.”

3. Linux:

• Using Terminal:
  • Open Terminal.
  • Type ifconfig -a and press Enter.
  • Look for the Ethernet interface (often named eth0).
  • The Ethernet address is listed under “ether.”

4. Mobile Devices (iOS/Android):

• iOS:
  • Go to Settings > General > About.
  • Scroll down to find the Wi-Fi Address. This is the MAC address of your device.
• Android:
  • Go to Settings > About phone.
  • Select Status or About device.
  • Look for Wi-Fi MAC address or Ethernet MAC address.

By following these steps, you can easily obtain Ethernet addresses on various devices and platforms. Understanding and documenting these addresses can aid in network management, troubleshooting, and ensuring network security.
