That's called the "MAC address" or "Hardware address". It's a unique set of numbers assigned to a network device. Anything that access the internet whether phones, wireless cards, computers, etc, all have a MAC address. The address with all one's (FF-FF-FF-FF-FF-FF) is the broadcast address. All devices on the physical segment will see and respond to a message with that destination.

1. The destination IP address is 255.255.255.255 2. The message comes from a client seeking an IP address 3. All host receive the message, but only a DHCP server replies
When a packet arrives at the network layer on the sender's device, it is encapsulated into a frame whose destination MAC address is all fs (FF-FF-FF...). The switch connected to the sender's device recognizes the all fs MAC address as a broadcast message and hence forwards it to all its ports.
Decipher the IP address means, obtain IP address using Hardware address, and basically we use RARP(Reverse address resolution protocol) to find out the IP address from hardware address.
A "MAC ADDRESS" (Media Access Control address), or an EHA (Ethernet Hardware Address), also known simply as "hardware address".
Hardware address is the MAC address. IPv4 is the IP address. The MAC address is assigned to each network device at the time it's manufactured and does not change. The IP address is manually assigned and can be changed.
mac-address
The hardware address or MAC address is encoded on the NIC by the manufacturer for unique identification of the NIC. This cannot be changed.... The IPv4 address is an internet address usually assigned by a DHCP server for each computer on a network. This address can be changed.
There are a couple other ways to refer to a MAC address. One could use the full name, media access control address, rather than the acronym. A MAC address could also be referred to a UAA, or universally administered address.
