Let’s say that you need to boost the number of MAC addresses from the default of 256 to 1,024 using Windows PowerShell.

The Virtual Switch Manager, the Windows Registry or Windows PowerShell can be used to increase the number of MAC addresses. The MAC Address range is also available in the Windows Registry on the following path: Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Virtualization (see Figure 2). This indicates a pool of 256 possible MAC addresses in the following range: * 00 to FF: The last byte shows a minimum of 00 and FF as maximum.In this case, the first IP address of the host was 192.168.7.47. The two lowest octets are converted to hexadecimal. * 07-2F: These two bytes come from the first IPv4 Address of the host.You will use this portion of the MAC address in all Hyper-V hosts. * 00-15-5D: Represents theMicrosoft IEEE Organizationally Unique Identifier.Let’s examine the address range in Figure 1. Then under Global Network Settings click on MAC Address Range (see Figure 1 below). To access the MAC Address Range, in Hyper-V Manager right-click the Hyper-V host name and choose Virtual Switch Manager from the shortcut menu. By default, Hyper-V dynamically assigns MAC addresses from this pool to each virtual network adapter at the time new virtual machines are created or when a new virtual network adapter is added to the VM. When Hyper-V is installed, a MAC address pool is created. The GUI and Windows PowerShell are used to explore different configuration options that can be very effective in managing stressful virtualized workloads. This article highlights more advanced network configuration options that greatly enhance the performance and security of Hyper-V hosts. Windows Server 2012 R2 Hyper-V has a plethora of new networking features that improve the functionality provided in previous Hyper-V versions before Windows Server 2012. That article also reviewed the initial Hyper-V network environment, including the configuration of external, internal, and private virtual switches, as well as the virtual local area network (VLAN) setting integration.
