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.
If you want to use another DHCP server in the network
other than the Vigor Router's, you can let Relay Agent help
you to redirect the DHCP request to the specified location.
Enable Server - Let the router assign IP address to every
host in the LAN.

IP address must be 192.168.1.2 or greater, but smaller than
192.168.1.254.
IP Pool Counts - Enter the maximum number of PCs that
you want the DHCP server to assign IP addresses to. The
default is 50 and the maximum is 253.
Gateway IP Address - Enter a value of the gateway IP
address for the DHCP server. The value is usually as same
as the 1st IP address of the router, which means the router is
the default gateway.
Lease Time – Enter the time to determine how long the IP
address assigned by DHCP server can be used.
DNS stands for Domain Name System. Every Internet host
must have a unique IP address, also they may have a
