 R6100 WiFi Router
Use Router as DHCP Server 
For most home networks, this check box is selected so that the router acts as a Dynamic 
Host Configuration Protocol (DHCP) server. 
Starting IP Address. Specify the start of the range for the pool of IP addresses in the 
same subnet as the router.
Ending IP Address. Specify the end of the range for the pool of IP addresses in the 
same subnet as the router.
Address Reservation
When you specify a reserved IP address for a computer on the LAN, that computer receives 
the same IP address each time it accesses the router’s DHCP server. Assign reserved IP 
addresses to servers that require permanent IP settings. 
Role of the Router as a DHCP Server
By default, the router acts as a DHCP server. The router assigns IP, DNS server, and default 
gateway addresses to all computers connected to the 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. 
You can specify the pool of IP addresses that the router assigns 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, define a range 
between 192.168.1.2 and 192.168.1.254, although you might want 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 Internet Setup screen; 
otherwise, the router’s LAN IP address)
Secondary DNS server (if you entered a secondary DNS address in the Internet Setup 
screen)
You can use another device on your network as the DHCP server, or specify the network 
settings of all of your computers.
To use disable the DHCP Server feature in the router:
1.
Select ADVANCED > Setup > LAN Setup.
