What is a MAC address?
A Media Access Control (MAC) address is a 48‑bit identifi er associated with the hardware of network equipment. The
MAC address may also be called the physical address because it is connec ted to the hardware of a device instead of its
software. The MAC address is displayed as a hexadecimal number in this format: 01-23-45-67-89-AB.
While it is possible to change the MAC address of a network device, it is not common practice to do so. For this reason,
MAC addresses are considered permanent. IP addresses are easily changed, so MAC addresses are a more reliable
method of identifying a specific device on a net work.
Routers with security capabilities may allow filtering of MAC addresses on networks. This allows a managed list of
devices to access the network, identified by their MAC addresses, as well as prevent access from unwanted devices. If
your network uses MAC address filtering, then be sure to add the MAC addr ess of the printer to the list of allowed
devices.
How do I find the MAC address?
Network devices have a unique hardware identification num ber to distinguish them from oth er devices on the network.
This is called the MAC (Media Access Control) address. Other devices sometimes use a type of MAC address called
Universally Administered Address (UAA).
When installing the printer on a network, make sure you select the printer with the correct MAC address.
The MAC address of the internal print server is a series of letters and numbers.
