Just what is a MAC Address?

Whether you work in a wired network office or a radio one, one thing is normal for both environments: It requires both network applications and hardware (cables, routers, etc.) to transfer information from your computer to another–or from a computer thousands of miles away to yours.

And finally, to get the information you would like correct TO YOU PERSONALLY, it comes down to addresses.

So not surprisingly, as well as an IP address (which is networks applications), there is also a hardware address. Usually it’s tied to your vital connection apparatus in your computer known as NIC, or the network interface card. The NIC is basically a computer circuit card which makes it possible for the pc for connecting to your network.

Information turns into an electric signal which can be transmitted on the network.

Hey Nick. Meet with Mac.
Every NIC has a hardware address that is known for Media Access Control, as a MAC. Where IP addresses are connected with TCP/IP (networking applications), MAC addresses are linked to the hardware of network adapters.

If it is made, a MAC address is provided to your network adapter. It’s hardwired or hard coded onto your pc ‘s network interface card (NIC) and is unique to it. Something called the ARP (Address Resolution Protocol) translates an IP address into a MAC address. The ARP is just like a passport that takes information from an IP address via a real piece of computer hardware.

IP addresses and MAC addresses working collectively yet again, that is hardware and applications working together.

Because of this, the MAC address may also be called a networking hardware address, the burnt-in address (BIA), or the physical address. Here’s a good example of a MAC address for an Ethernet NIC: 00:0 95:9d:68:16.

As you have likely seen, the MAC address itself does not seem anything like an IP address (see yours here). The MAC address is a sequence of typically six sets of two- characters or digits .

Some well known makers of NICs or network adapters are Belkin Dell, Nortel and Cisco. These producers all area a unique amount sequence (called the Organizationally Unique Identifier or OUI) in the MAC address that identifies them as the manufacturing company. The OUI is usually correct in the very front of the address.

As an example, consider a network adapter together with the MAC address “00-14-22-012345.” The OUI for the production of the router is the primary three octets–“00-14-22.” Here are the OUI for other some well known producers.

Dell: 00-14-22

Nortel: 00-04-DC
Cisco: 00-40-96
Belkin: 00-30-BD
It is not unusual for the bigger manufacturers of networking gear to own more than one set of OUIs.

MAC and networks addresses.
All devices to a single network subnet have MAC addresses that are distinct. MAC addresses are extremely useful in diagnosing network issues, like problems with IP addresses.

Since they never change, rather than a dynamic IP address, which may alter from time to time, MAC addresses are ideal for network analysis. To get a network administrator, a MAC address is made a more dependable method to recognize senders and receivers of information on the network by that.

Wireless Routers and MAC Filtering
On wireless networks, an activity called MAC filtering is a security measure to stop unwanted network access by intruders and hackers. In MAC address filtering, the router is configured to accept traffic only. Computers whose MAC addresses are approved, by doing this is going to not be unable to speak through the network when DHCP gave them a brand new IP address.

A hacker who is hijacked a network IP address will be blocked because their MAC address WOn’t be to the list that is approved and is going to be filtered out.
