Summary
Click this to display a summary table for the IP address pool. See Section 8.2.1
on page 76 for more details.
The ZyXEL Device is pre-configured with a pool of IP addresses for the DHCP
clients (DHCP Pool). See the product specifications in the appendices. Do not
assign static IP addresses from the DHCP pool to your LAN computers.
IP Pool Count This field specifies the size, or count of the IP address pool.
Lease Time This is the period of time DHCP-assigned addresses is used.
DHCP automatically assigns IP addresses to clients when they log in. DHCP
centralizes IP address management on central computers that run the DHCP
server program. DHCP leases addresses, for a period of time, which means that
past addresses are “recycled” and made available for future reassignment to
other systems.
