The Future of the MAC address
A MAC address is made up of 6 bytes written as 12 hex digits. For example: 00-80-C8-E3-4C-BD. Of this address, the first 3 bytes (00-80-C8) identifies the card’s manufacturer. The IEEE is the body that assigns manufacturers their IDs, called Organizationally Unique Identifiers. So, this leaves 3 bytes which can be assigned by the manufacturer [...]

How many meters of patch cable can we use to connect a LAN?

The distance limitation is between devices that generate the signal.
