How Do I Find My Machine ID (Host ID)?

Tags: Sapphire

Your Machine ID is your Ethernet ID/MAC address. It consists of 6 pairs of numbers and letters A-F. You may see these pairs un-separated (d312a930bc7f), separated by colons (d3:12:a9:30:bc:7f) or separated by dashes (d3-12-a9-30-bc-7f). To find your Machine ID, please follow the steps below.

On Windows

  • Go to the Start menu, then in the search box type “cmd” and hit Enter.
  • In the cmd window, type “ipconfig /all”.
  • Find the line that reads “Physical Address”. This is your Machine ID.

On Mac

  • Go to System Preferences > Network and select your active network interface (e.g., Ethernet)
  • From the list on the left. Click on ‘Advanced…’, then on ‘Hardware’.
  • The Machine ID is listed under “MAC Address”.

On Linux

  • Open a terminal/shell window, and type “ifconfig”.
  • Look for “Hwaddr” under eth0. This is your Machine ID.
