Is the registration of virtual addresses associated with virtual machines permitted?
You may register virtual addresses associated with virtual machines provided you follow these guidelines to avoid conflicts. First, make sure that the virtual hardware (or MAC) address you intend to use will not conflict with any address that may be assigned to hardware by a manufacturer. Since addresses assigned to hardware may not be modifiable, virtual machines must avoid potential conflicts with hardware when selecting an address. Determine if your virtual environment assigns addresses from a pool with one or more assigned OUIs. The OUI is the first three bytes in the address. For example, the OUI of the address 00:de:ad:be:ef:00 is 00-de-ad. You can look up OUI assignments on the IEEE website http://standards.ieee.org/regauth/oui/index.shtml. Check with the listed entity to ensure that the OUI is for use by virtual machines. For example, the Xen hypervisor has the assigned OUI 00-16-3e that is designated for use by virtual machines per a Xen website: http://wiki.xensource.com/xenw
