To work correctly, each network interface has to have an address that is unique in its local segment of media. That way, any receiving interface can tell what kind of destination address it is reading after just reading one byte. The broadcast address uses all 1s binary or all FF hex. The first byte of a multicast address is odd, such as 01, 03, 05, etc. A unicast address’s first byte will be even, like 02, 04, 06, etc. The way to identify which address type you are viewing is simply look at the first byte. There are three types of MAC addresses: Unicast, Multicast, and Broadcast. They have already planned to extend the MAC address space to 64 bits and will call it EUI-64. Their current projection is that the amount of addresses available with 48 bits (over 281 Trillion) will last until 2100. They show up in most IEEE 802 networks including: 802.3 (as well as Ethernet II), 802.5, 802.11 (Wi-Fi), 802.15 (Bluetooth), and the ITU-T G.hn standards. MAC addresses act as the physical addresses for local communications. It is written in hexadecimal characters as shown below: EUI stands for Extended Unique Identifier.

These MAC addresses are 48 bits or 6 bytes long, so they are also known as MAC-48 or EUI-48. Scroll down until you see the Wi-Fi MAC address.While Apple has created many fine things, they were yet to be created themselves when Xerox PARC scientists created Media Access Control addresses.

Look for Wi-Fi address.this is your MAC address.The MAC address should contain 6 sets of HEX numbers for example: 00:A0:23:C9:12:FF The wireless network adapter is labeled wireless, but also look for something like the following example: Intel Pro10/100/1000 PCI Adapter.Īpproximately 15 lines below the adapter name is the MAC Address. It is important to find the correct device. Scroll down to find your network adapter note that many devices may be listed. Click on the + sign to the left of Network.Click on the + sign to the left of Components.For Windows 10: Click in search window and then type:.For Windows 7: Click the Start Menu and then select:Īll Programs > Accessories > System Tools > System Information then go to step 3.Look for your network adapter in the list and the physical address is the MAC number needed. In the black window that pops up type: getmac /v The MAC address is a number used by network adapters to uniquely identify themselves on a LAN a MAC address is a 12-digit hexadecimal string and looks something like: 00:A0:23:C9:12:FFĮasy way: Click the Start Menu and then select All Programs > Accessories > Command Prompt.
