Use Router As Dhcp Server; Address Reservation - NETGEAR AC1200 JR6100 User Manual

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.
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 the LAN Setup 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 must 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.
• 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.
The router delivers the following parameters to any LAN device that requests DHCP:
• An IP address from the range that you have defined
• Subnet mask
• Gateway IP address (the router's LAN IP address)
• DNS server address (if you entered a primary DNS address in the Internet Setup screen;
otherwise, the router's LAN IP address)
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.
2. Clear the Use Router as DHCP Server check box.
3. Click the Apply button.
4. (Optional) If this service is disabled and no other DHCP server is on your network, set your
computer IP addresses manually so that the can 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. Assign
reserved IP addresses to computers or servers that require permanent IP settings.
