A MAC address is only relevant to the local area network (LAN) to which the device is connected and is not part of the data stream when packets leave the device's network. On the other hand, an IP address determines how an internet-connected device communicates globally and is a layer 3...
and a MAC address is a physical address used for communication locally within a single network. IP addresses operate at the third layer of the OSI model,the network layer, while MAC addresses are used at the second layer,the data link layer. ...
MAC Address Stands for "Media Access Control Address." A MAC address is a hardware identification number that uniquely identifies each device on anetwork.

By default, a MAC address is written in this format using colons as delimiter.Xrepresents a hexadecimal digit. XX:XX:XX:XX:XX:XX MAC addresses can also be written using hyphen as delimiter. XX-XX-XX-XX-XX-XX MAC addresses can also use dots as delimiter. ...
A MAC (Media Access Control) address is a unique identifier assigned to anetwork interface controller(NIC) that ensures data reaches the intended recipient. Most MAC addresses are 6-byte(48-bit) strings of 12 hexadecimal digits separated by colons or dashes. The first three bytes identify the ...
An example of a MAC address is 30-65-EC-6F-C4-58.Some manufacturers, such as Dell, place a unique identifier in the MAC address, which is called the Organizationally Unique Identifier (OUI), and identifies the manufacturer. The OUIs of some well-known firms are:...
What is a MAC address used for? All devices on the same networksubnethave different MAC addresses. MAC addresses are very useful in diagnosing network issues such as problems with IP addresses. MAC addresses are useful for network diagnosis because they never change, as opposed to a dynamic IP...
