Using The Router As A Dhcp Server; Address Reservation - NETGEAR WNDR3400 - N600 Wireless Dual Band Router User Manual

Using the Router as a DHCP Server

By default, the router functions as a DHCP server, allowing it to assign IP, DNS server, and default
gateway addresses to all computers connected to the router's LAN. The assigned default gateway
address is the LAN address of the router. The router assigns IP addresses to the attached computers
from a pool of addresses specified in this screen. Each pool address is tested before it is assigned to
avoid duplicate addresses on the LAN.
For most applications, the default DHCP and TCP/IP settings of the router are satisfactory. Click
the link to the online document
DHCP and information about how to assign IP addresses for your network.
Specify the pool of IP addresses to be assigned by setting the starting IP address and ending IP
address. These addresses should be part of the same IP address subnet as the router's LAN IP
address. Using the default addressing scheme, you should define a range between 192.168.1.2 and
192.168.1.254, although you might wish to save part of the range for devices with fixed addresses.
The router delivers the following parameters to any LAN device that requests DHCP:
• An IP Address from the range you have defined
• Subnet Mask
• Gateway IP Address (the router's LAN IP address)
• Primary DNS Server (if you entered a primary DNS address in the Basic Settings screen;
otherwise, the router's LAN IP address)
• Secondary DNS Server (if you entered a secondary DNS address in the Basic Settings screen)
To use another device on your network as the DHCP server, or to manually configure the network
settings of all of your computers, clear the Use Router as DHCP Server check box. Otherwise,
leave it selected. If this service is not selected and no other DHCP server is available on your
network, you will need to set your computers' IP addresses manually or they will not be able to
access the router.

Address Reservation

When you specify a reserved IP address for a computer on the LAN, that computer always
receives the same IP address each time it accesses the router's DHCP server. Reserved IP
addresses should be assigned to computers or servers that require permanent IP settings.
To reserve an IP address:
