This article provides information about System Center - Virtual Machine Manager (VMM) default MAC addresses, and describes how to create and manage a custom MAC address pool.
Jan 21, 2014 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. Then under Global Network Settings click on MAC Address Range (see Figure 1 below). Let’s examine the address range in Figure 1. 00-15-5D: Represents theMicrosoft IEEE Organizationally Unique Identifier. You will use this portion of the MAC. The source of the MAC addresses comes from a default MAC Address Pool of Hyper-V that you can see through the Virtual Switch Manager settings, specifically in the MAC Address Range section, as shown in the figure below. According to Microsoft documentation, the number of dynamic MAC addresses that a Hyper-V host can produce is 256.
VMM uses static MAC address pools to automatically generate and assign MAC address to VMs. This article describes default MAC address pools in the VMM fabric and explains how to create custom pools.

Access: Access is a relational database management system that comes with the Professional editions of Office for Windows. You can’t get Access on the Mac, so if you (or your company) works with Access databases, you’re out of luck.And while we’re on the subject, there are also a couple of higher end “Office-adjacent” apps that aren’t available on macOS:. Mac os excel shortcuts.
MAC pool name | Environment | Default range |
---|---|---|
Default MAC address pool | Hyper-V | 00:1D:D8:B7:1C:00 – 00:1D:D8:F4:1F:FF |
Default VMware MAC address pool | ESX/ESXi | 00:50:56:00:00:00 – 00:50:56:3F:FF:FF |
Before you start
Before you create a custom MAC pool note that:
- If you want to divide one of the default pools into smaller custom pools, you must first delete the default MAC address pool or the default VMware MAC address pool. You must delete the default pool to avoid duplicate MAC address assignments.
- The first three octets of the beginning and ending MAC address must be the same.
- You must enter a valid hexadecimal values between 00 and FF.
- The ranges that you specify cannot overlap.
- The address range must not have the multi-cast bit set to 1. For example, you cannot use addresses that start with X1, X3, X5, X7, X9, XB, XD, or XF, where X is any value.
- To avoid conflicts with addresses reserved by Microsoft, VMware, and Citrix, do not use the following prefixes:
- Reserved for Microsoft: 00:03:FF; 00:0D:3A; 00:12:5A; 00:15:5D; 00:17:FA; 00:50:F2; 00:1D:D8 (except for the 00:1D:D8:B7:1C:00 – 00:1D:D8:F4:1F:FF range that is reserved for VMM)
- Reserved for VMware: 00:05:69; 00:0C:29; 00:1C:14; 00:50:56 (except for the 00:50:56:00:00:00 – 00:50:56:3F:FF:FF range that is the reserved as the default VMware static range)

Create a custom pool
- Click Fabric > Networking > MAC Address Pools > Home > Show > Fabric Resources > Create > Create MAC Pool.
- In Create MAC Address Pool Wizard > Name and Host Group specify a name and description. In Host Group select the host groups that should use the pool.
- In MAC Address Range specify the start and end addresses.
- In Summary review the settings and click Finish. When the job shows as Completed verify pool in MAC Pools.
Release IP addresses
In some circumstances you might want to remove addresses from the MAC pool. For example if a host that was assigned an IP address during bare metal deployment is removed from VMM management, or if a VM goes into a missing state because it was removed outside VMM.
- Click Fabric > Networking > MAC Address Pools > Home > Show > Fabric Resources.
- In MAC Pools click the pool you want to modify > Properties.
- In Inactive addresses select the addresses you want to release.
