About MAC Addresses
• MAC (Media Access Control) addresses are unique identifiers for network interfaces
• The first 3 octets (6 hex digits) identify the manufacturer (OUI)
• The last 3 octets are assigned by the manufacturer
• Locally administered addresses have the second bit of the first octet set to 1
• This lookup uses a local database which may not include all manufacturers
