MAC Address and RLM License File

  • Updated

For Maxon to issue an RLM license file, you need to provide the ethernet address (also known as the "MAC Address" or "Host Id") and the host name of the computer you have designated as your license server. The MAC address is a 12-digit hexadecimal number. It can be displayed in a few different ways, for example bcaec524d7c9, BCAEC524D7C9 or BC-AE-C5-24-D7-C9. 

There is a MAC address for each network adaptor on your system, including "onboard" ethernet adaptors (built into the machine's motherboard), Ethernet adapters plugged in to the PCI slots of the machine's motherboard and mobile USB network adaptors (Wi-Fi, Bluetooth, etc..). 

Using a mobile network device can often be the best choice as it allows you to easily move your RLM floating licenses to a new license server machine if, for example, your server machine has a hardware failure. 

Obtaining your license server's MAC address 

To obtain a list of MAC addresses on your Windows machine, open a command prompt and run the command  following command and notice the MAC address for each network adaptor is listed in the 3rd column.

getmac /v

Alternatively, you can run the following command and the MAC address for each network adaptor is shown with the label "Physical Address":

ipconfig /all

On Linux or macOS, use the command :


and look for output similar to: 

eth0 Link encap:Ethernet HWaddr 00:11:22:33:44:55 

The MAC address is the string of 6 pairs of 2 hexadecimal digits. 

If you are unsure which network adaptor to use, simply run getmac /v (Windows) or ifconfig (Linux, macOS) and email a screenshot of the output to and we will select an appropriate one for you.
