These are some advantages of the network database:
•
Generally, you do not need to enter an IP address or a MAC address. Instead, you can
just select the name of the desired PC or device.
•
There is no need to reserve an IP address for a PC in the DHCP server. All IP address
assignments made by the DHCP server are maintained until the PC or device is removed
from the network database, either by expiration (inactive for a long time) or by you.
from the network database, either by expiration (inactive for a long time) or by you.
•
There is no need to use a fixed IP address on a PC. Because the IP address allocated by
the DHCP server never changes, you do not need to assign a fixed IP address to a PC to
ensure that it always has the same IP address.

A PC is identified by its MAC address—not its IP address. The network database uses
the MAC address to identify each PC or device. Therefore, changing a PC’s IP address
does not affect any restrictions applied to that PC.
