What does MAC address tell you?

The MAC address (short for media access control address) is the worldwide unique hardware address of a single network adapter. The physical address is used to identify a device in computer networks. Since MAC addresses are assigned directly by the hardware manufacturer, they are also referred to as hardware addresses.

Is sharing MAC address safe?
