If you don’t know what a MAC address is, then you can read but you probably shouldn’t implement the steps below. This brief tutorial is going to show students and new users an easy way to change the Ubuntu system’s MAC addresses. There are many reasons one might want to change a system MAC address. A common one is to give a system a new identity on a given network. I resolved a very strange issue a few years back by changing the system MAC address. I was troubleshooting a system that kept coming up on a network with duplicate IPs from the DHCP server. I researched but couldn’t see anything that was causing the issues. I went through the usual sysadmin tricks to get the system up with a different IP but to no avail. The way I ended up resolving the issue was to change its MAC address and the DHCP server assigned a different IP, which then fixed the issues. So, if you find yourself in similar situations, changing the system MAC address might help. To change a Ubuntu system MAC address, follow the steps below:
