By using MAC addresses for identification, devices can still be identified even if their IP address changes.ДЇinding a MAC address on network manually often requires using a series of commands and knowing a lot about the specific system youвЂ™re working with beforehand. Filtering is a process by which strangers are prevented from accessing a network while letting the people who need access get through. MAC addresses are also useful when it comes to filtering on wireless networks. If they donвЂ™t match, then the packet is discarded. If the addresses match, then the packet is processed. When a network adapter receives a packet, it checks to see if the packetвЂ™s destination MAC address matches its own. When packets are sent on the ethernet, theyвЂ™re sent from a MAC address and to another MAC address. The MAC address exists in addition to the IP address assigned by the local server or router and is essential for the functionality of network protocols like IP and TCP. While MAC address is the most common name, it is also sometimes called a physical address, a burned-in address, or a hardware address.Д®very individual piece of hardware on your local network has a MAC address typically assigned by the manufacturer of the device then stored on the hardware.
