Detailed explanation-1: -A MAC address consists of 12 hexadecimal digits, usually grouped into six pairs separated by hyphens. MAC addresses are available from 00-00-00-00-00-00 through FF-FF-FF-FF-FF-FF. The first half of the number is typically used as a manufacturer ID, while the second half is a device identifier.
Detailed explanation-2: -The first half of any MAC address is referred to as the OUI, or Organisational Unique Identifier; this arrangement of characters are unique to a particular manufacturer and can be used to identify the manufacturer simply by looking at these characters.
Detailed explanation-3: -The first three bytes (pairs of hexadecimal characters) of any unicast address contain that vendor address component of the MAC address. The remaining three bytes carry the serial number of that vendor’s interface card.
