Explanation:
Detailed explanation-1: -The first three bytes (00:D0:59) identify the manufacturer of the card; because only this manufacturer can use this address, it is known as the Organizational Unique Identifier (OUI).
Detailed explanation-2: -The manufacturer then assigns a unique value for the last 3 bytes, which ensures that every MAC address is globaly unique. Every hexadecimal character represents 4 bits, so the first six hexadecimal characters represent the vendor (Hewlett Packard in this case).
