dot decimal notation. The subnet mask indicates what part of the IP address is the same for
all computers on the network.
DHCP Server
Mode Select what type of DHCP service the Zyxel Device provides to the network. Choices are:
DHCP Relay - the Zyxel Device routes DHCP requests to one or more DHCP servers you
specify. The DHCP server(s) may be on another network.
DHCP - the Zyxel Device assigns IP addresses and provides subnet mask, gateway, and DNS
server information to the network. The Zyxel Device is the DHCP server for the network.
These fields appear if the Zyxel Device is a DHCP Relay.

every IP address allowed by the interface’s IP address and subnet mask, except for the first
address (network address), last address (broadcast address) and the interface’s IP address.
Pool Size Enter the number of IP addresses to allocate. This number must be at least one and is
limited by the interface’s Subnet Mask. For example, if the Subnet Mask is 255.255.255.0 and
Start IP is 10.10.10.10, the Zyxel Device can allocate 10.10.10.10 to 10.10.10.254, or 245 IP
addresses.
If this field is blank, the Start IP must also be blank. In this case, the Zyxel Device can assign
