If you access WiFi networks from your laptop, these networks may sometimes want to know your laptop’s MAC Address. Some wireless networks restrict access to only those computers they know, so the network asks for some piece of identification. That piece of ID is the wireless networking hardware’s MAC Address.

No two MAC Address numbers are identical, and the MAC Address is very difficult to fake. Microsoft remote desktop for mac not working. By using the MAC Address, a wireless network can restrict access to only those computers that are known and registered.

The MAC Address is 12 digits long, broken up into pairs, like this: 12:34:56:78:9A:BC. It’s a base-16 value (also called hexadecimal), so the letters A through F are also considered to be numbers.

• Dec 11, 2019  There are a few ways to find the IP address and MAC address of a computer running Microsoft Windows. You'll need these details when setting up software, diagnosing a network problem, configuring MAC address filtering, and other tasks. These directions are for finding the local IP address Windows is using.
• Issue 1: Media Access Control Address. A network adapter, also called a Network Interface Card or NIC, is equipped with a unique identifier known as the Media Access Control (MAC) address.This address can be used by routers and switches to control access to a network.

If the MAC Address is necessary to connect to a specific network, hand it over to the network manager or human in charge. That person will happily add your laptop’s address to the list of allowed computers so that you can use the network.

Every network device or interface, such as your laptop's Wi-Fi adapter, has a unique hardware ID called the MAC (or 'media access control') address. You can find the MAC address for your network.

Here’s how to find your laptop’s MAC address:

1. Choose Control Panel from the Start menu, and then choose Network Connections.

   The Network Connections window opens.

2. Open your Wireless Network Connection icon.

   This step displays a Status window.

3. Click the Support tab.

4. Click the Details button.

   A Network Connection Details dialog box appears. Locate the item labeled Physical Address, which is the MAC Address number.

5. Copy down that number.

6. Close the various dialog boxes, windows, and whatnot.

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.

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.

Default MAC address pool settings:

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

1. Click Fabric > Networking > MAC Address Pools > Home > Show > Fabric Resources > Create > Create MAC Pool.
2. 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.
3. In MAC Address Range specify the start and end addresses.
4. 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.

Mac Address Microsoft

1. Click Fabric > Networking > MAC Address Pools > Home > Show > Fabric Resources.
2. In MAC Pools click the pool you want to modify > Properties.
3. In Inactive addresses select the addresses you want to release.
