Static allocation
—The network administrator chooses
the IP address to assign to the client and the DHCP server sends
it to the client. A static DHCP allocation is permanent; it is done
by configuring a DHCP server and choosing a
Reserved
Address
to correspond to the
MAC Address
of
the client device. The DHCP assignment remains in place even if
the client logs off, reboots, has a power outage, etc.
Static
allocation of an IP address is useful, for example, if you have
a printer on a LAN and you do not want its IP address to keep changing,
because it is associated with a printer name through DNS. Another
example is if a client device is used for something crucial and
must keep the same IP address, even if the device is turned off,
unplugged, rebooted, or a power outage occurs, etc.
