In order to communicate or transfer the data from one computer to another computer we need some address. In Computer Network various types of address are introduced; each works at different layer. Media Access Control Address is a physical address which works at Data Link Layer. In this article, we will discuss about addressing in DLL, which is MAC Address.
MAC Address or media access control address is a unique ID assigned to network interface cards (NICs). It is also known as a physical or hardware address. It identifies the hardware manufacturer and is used for network communication between devices in a network segment. MAC Address usually consists of six groups of two hexadecimal digits. The wireless MAC address for your Echo can be found at the bottom of the Echo Setup screen in the Alexa app. From the Amazon app, visit the Home screen. Choose Settings. Choose My Fire TV or Device.

The wireless MAC address for your echo is seen at the bottom of the Echo Setup screen in your Alexa app and this is how you can find your MAC address for your echo device. Amazon launched other devices also, Amazon fire TV is the also well known and most used device. In addition to adding a list of authorized MAC addresses to the individual APs that make up your wireless network, you can centrally maintain a list of authorized MAC addresses via a RADIUS server. Because many operating systems allow you to locally set your MAC address on your network card, this security is only light security — like WEP.

MAC Addresses are unique 48-bits hardware number of a computer, which is embedded into network card (known as Network Interface Card) during the time of manufacturing. MAC Address is also known as Physical Address of a network device. In IEEE 802 standard, Data Link Layer is divided into two sublayers –
- Logical Link Control(LLC) Sublayer
- Media Access Control(MAC) Sublayer
