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 firewall. The DHCP assignment remains in place even if the client
disconnects (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 firewall is used for something crucial and must keep the
same IP address, even if the firewall is turned off, unplugged,
rebooted, or a power outage occurs.
