For network devices, it's a MAC address. MAC stands for 'media access control' and it's a unique identifier that's present in all hardware that interfaces with a traditional computer network. The device that manages DHCP (or assigning IP addresses to devices) often asks the devices for their MAC addresses and then gives them an IP address. Usually MAC addresses are written as something like 00:0a:5e:1a:8d:a2 and they use hexidecimal notation (allowed numbers 0-9, and letters A-F).
Dotted-decimal notation
802.11 use MAC addresses, which are the same as IP addresses in some networks
This 48-bit address space contains potentially 248 or 281,474,976,710,656 possible MAC addresses.
Address Resolution Protocol (ARP)ARP is primarily used to translate IP Addresses to Ethernet MAC Addresses.
yes they do.

Routers don't use MAC addresses for routing. They use IP address.
A MAC address is unique to your ethernet card. MAC addresses are used within an Ethernet network to uniquely identify the source and destination of Ethernet frames. ARP (Address Resolution Protocol) is used on IP networks to map IP addresses to MAC addresses within an Ethernet network.

if the mac addresses are broadcrk securiwoasting the there is no need of net
