Any one of the found MAC addresses can be used as the "Ethernet hostid" for licensing. If you execute the script and redirect the output to an HTML file, you are left with an HTML file that shows the IP, the full MAC address, and a link to the IEEE OUI lookup page. I haven't tested this with Vivado specifically, but it works with other vendors that use FlexNet's generic lmgrd. ![]() This helps in determining the client by way of NIC manufacturer. ![]() (On a physical system or a full VM, it would also be possible to rename eth0 to something else, then create a virtual eth0 in its place, but this might not work with WSL2 due to the way it's architectured. ![]()
