Introduction

Mac address, short for Media Access Control address, is a hardware address that uniquely identifies each node of a network.

It means, in a local area network (LAN) or other network, the MAC (Media Access Control) address is your computer's unique NIC number. (On an Ethernet LAN, it's the same as your Ethernet address.) When you browser the Internet with your computer (or host as the Internet protocol thinks of it), a correspondence table relates your IP address to your computer's macAddress on the LAN. This table often organized by your computer's router or your ISPs.

The MAC address is used by the Media Access Control sublayer of the Data-Link Layer (DLC) of telecommunication protocols. There is a different MAC sublayer for each physical device type. The other sublayer level in the DLC layer is the Logical Link Control sublayer.

This paper will propose methods of scanning macAddress and change macAddress.

2 Troubleshooting of spoofing macAddress by a-macaddress change

2.1 Not getting the new MAC address just updated?

macAddresses must obey IANA Number Assignments database. For example, "00-00-00-00-00-00" is not a valid MAC address, therefore, even though you can update this address, it may be rejected by the NIC device driver because it is not valid, and Phisical macAddress will be used instead. Even "00-00-00-00-00-00" may be accepted by the NIC device driver, however, the device will not function.

You can read the information at http://www.iana.org/assignments/ethernet-numbers.htm. The latest MAC address Organization Unique Identifier (OUI) listing is available at http://standards.ieee.org/regauth/oui/oui.txt.

2.2 Still having problem after I choose right macAddress

You ISPs or router may demand for special mac address or special macAddress-ip combination. At this time, you can use a-macaddress change to scan mac address first, then use the scanned mac address-ip combination to spoof a new mac address. Make sure there is no two computer with same mac address-ip combination active together, other there may be network problem.
