Current Pool 

Summary

Click this to display a summary table for the IP address pool. See 

 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.
