Property Management: Getting MAC Address From Various Sources


The Media Access Control(MAC) address can be used to identify computers on the network.  MAC address composes of twelve(12) alpha-numeric digits ranging from 0 to 9 and A to F.  It is usually written in six groups of two digits separated by hyphens( - ), colons( : ), or spaces.  The following are examples of MAC addresses:

001E35F5589B

00-20-E0-89-4F-DC

00:d0:59:a3:29:c5

00 11 b5 47 07 6f


While most desktop computers have only one MAC address for the wired network card, most laptops should have two MAC addresses--one for the wireless network card and one for the wired network card.  It is important that both wired and wireless MAC addresses be recorded.

The purpose of this article is to show the user how to recognize and obtain MAC addresses from product packaging.  If the MAC address cannot be obtained from the packaging, it is necessary to power on the computer and obtain the MAC address there.  Please follow the GROK article below to obtain the MAC address from within the Operating System:
