What is MAC Address ?

  • A Media Access Control (MAC) address is a 48-bit address stored in the network Interface card.
  • It is used for communication between two hosts in an Ethernet environment.
  • It is nothing but a hardware /physical address of a computer.
  • A MAC address is supposed to be globally unique and this will not be duplicated.
  • The 48 bit contains – First 24 bits ( User ID -> Card Buyer ID ) + second 24 bits (card manufacturer)
  • The address is written in the form of 12 hexadecimal digits. For example, consider the following MAC address:
    • D8-D3-85-EB-12-E3
