MAC Address Format
A complete MAC address consists of 48 bits (6 bytes) and is typically represented in hexadecimal format with each byte separated by a colon or a hyphen. For JM-DATA GmbH devices, the MAC address would look like:
0C:B9:12:XX:XX:XX
The first three bytes (0C:B9:12) identify the manufacturer as JM-DATA GmbH, while the last three bytes are unique to each device.
