![]() You can do this via Windows Admin Center, Hyper-V Manager, or using PowerShell (script below).ģ) Turn On the VM. ![]() To generate a new MAC address for the VM which is set to use a static MAC address, you want to go through the following steps:Ģ) Set the VM to use a dynamic MAC address. The challenge is, all virtual machines are already set to use a static MAC address. I was working recently on a scenario where I want to change the default MAC address pool on each Hyper-V host, and then I want to force all virtual machines to get a new MAC address from the new pool. The last octet ( FF) is generated from the range 0x0 – 0xFF. The next 2 octets ( 14-22) are generated by the last two octets of the IP address that was first set up on the Hyper-V server. They all use the same first three octets: ( 00-15-5D), as Microsoft owns that prefix. Each Hyper-V host generates a default pool. You can also configure this range yourself if you want to. If you use static MAC addresses, you can use the MAC address that was generated initially for you, or you can manually specify the MAC address to use, but once a static MAC address is set on a VM, Hyper-V will never change it.Įach Hyper-V server has a MAC address range that it uses for generating new dynamic MAC addresses. ![]() Hyper-V by default uses a dynamic MAC address – which means that Hyper-V will generate an initial MAC address for each network adapter, either for VM (vmNIC) or for the host (vNIC), and it will regenerate the MAC address if it believes it is necessary. Since Hyper-V’s inception back in 2008, you can configure a virtual machine to use a dynamic or a static MAC address for any given virtual network adapter. ![]()
