 IM0ABCDEFABCDEF0 as hwid for MAC address controlled licenses, where AB:CD:EF:AB:CD:EF is MAC address.

Use IM0ABCDEFABCD**0 if you want to recognize all MAC addresses of type AB:CD:EF:AB:CD:xx

Use IM0ABCDEFABCDEF0 as HW ID where AB:CD:EF:AB:CD:EF is MAC address.

Use IM0ABCDEFABCD**0 if you want to recognize all MAC addresses of type AB:CD:EF:AB:CD:xx
