Private IP addresses can be assigned automatically to LAN clients using Dynamic Host 
Configuration Protocol (DHCP), or manually assigned. The DHCP server can either be the 
router (the most common case), or a separate server, that hands out IP addresses to DHCP 
clients. 
Alternatively, static IP addresses can be manually configured on LAN clients as part of their 
network settings. No matter how IP addresses are configured, it is important that no two 
devices get the same IP address. If both DHCP and static assignment are used on a network, it 
is important to exclude the static IP addresses from the DHCP IP pool. For example, if your 
LAN uses the 192.168.1.x subnet and you have 20 DHCP clients and 20 static IP clients, you 
could configure 192.168.1.10 as the Start IP Address, 50 as the IP Pool Counts (enough for the 
current number of DHCP clients, plus room for future expansion), and use addresses greater 
than 192.168.1.100 for static assignment.

192.168.1.1). 
Subnet Mask - The subnet mask, together with the IP Address 
field, indicates the maximum number of clients allowed on 
the subnet. (Default: 255.255.255.0/ 24). 
DHCP Server 
Configuration 
DHCP stands for Dynamic Host Configuration Protocol. The 
router by factory default acts a DHCP server for your network 
so it automatically dispatch related IP settings to any local 
user configured as a DHCP client. It is highly recommended 
that you leave the router enabled as a DHCP server if you do 
not have a DHCP server for your network. 
Disable Server – Let you manually assign IP address to every
