Something You Should Know about MAC Address

The acronym for MAC is Media Access Control. It is considered to be a unique identifier for network interfaces. It would be utilized as a network address for most IEEE 802 network technologies. Sometimes it would be known as the BIA (burned-in address) or the EHA (Ethernet hardware address). Among its applications are the 802.11 wireless networks, Ethernet, and Bluetooth. I would say that if you wish to have more knowledge regarding the MAC Address, acquire the training offered by the SPOTO program.

What Is A MAC Address?

The MAC address would be usually assigned by the manufacturer of a NIC (Network Interface Controller), and it would be stored in the hardware. The NIC is a computer circuit card which would be allowed a computer to connect to a network. During network communication, the ARP (Address Resolution Protocol) for the IPv4 (Internet Protocol Version 4) or the NDP (Neighbor Discovery Protocol) for IPv6 would be translating the IP into a NIC.

The MAC address is created following the rules of the three numbering namespaces, which would be managed by the IEEE (Institute of Electrical and Electronics Engineers). The format is six sets of two digits or characters, which is separated by hyphens. An example of a MAC address is considered to be 30-65-EC-6F-C4-58. If you wish to obtain more knowledge about the MAC Address, you should check out the training courses which would be offered by the SPOTO MAC Certification programs.

What Is A MAC Address Utilized For?

One of the applications of MAC addresses is considered to be in the filtering process on wireless networks. To prevent strangers from accessing a network, the router is considered to be set to accept only specific MAC addresses. In this way, if the IP address changes, for example in the case of dynamic IP addresses, the MAC address could be still identified the device.

Filtering could be utilized to track network users and to limit their access. It could also have other uses, like the identification when a stolen device would be connected to the network. For these reasons, many companies, as well as institutions, would require the MAC addresses of their members’ devices. Therefore, it would be considered to be quite important for device owners not to reveal their MAC addresses to anyone, except to authorized personnel. MAC addresses could also be utilized in data recovery to connect to a wireless device.

How To Find MAC Address?

If a person needs to know about how to find MAC address on Windows 7, or a MAC address on Windows 8, all that would be necessary, is to open a cmd window, and once the Command Prompt is opened, they should type in ipconfig /all and press enter. A set of labels as well as values will appear. The MAC address would be listed under the description of Physical Address.

In a Mac computer, the process for finding the MAC address would be as follows: 

Go to utilities, and start the Terminal app. Type network setup lists all hardware ports. The computer will display all network interfaces as well as their MAC addresses (Ethernet Addresses). In an iPhone, MAC address would be found on the select in the home menu: Settings à General à About. The iPhone MAC address would appear under the setting WiFi Address.

How To Change The MAC Address?

In general MAC addresses couldn’t be modified, as they would be defined by the manufacturer. On the other hand, it is possible to change IP address MAC, and utilize other techniques for MAC addresses.
