DHCP, DNS and Time

3.1 DHCP

DHCP (Dynamic Host Configuration Protocol) is a method of automatically assigning IP address, subnet mask, default gateway and DNS server IP address to hosts on the LAN. This router provides an in-built DHCP Server. In addition, a DHCP Relay is available to relay the DHCP Requests to a DHCP Server on another port.

3.1.1 DHCP Server

The DHCP server assigns and manages IP addresses from a specified address pool to DHCP clients. When a DHCP server receives a request from a DHCP client, it returns the configuration parameters (such as an IP address, a MAC address, a domain name, and a lease for the IP address) to the client in a unicast message format. Because the DHCP server maintains all the configurations parameters, an administrator only needs to update the central DHCP Server when any configuration parameter is to be changed.

Compared to the static assignment where the client owns the address, dynamic addressing by the DHCP server leases the address to each client for a defined period of time. During the life cycle of the lease, the client is guaranteed to have a unique IP address that can last for the entire period. If the client needs to renew the lease from the server it can do so before the expiration of the lease. The client may also decide at any time that it no longer wishes to use the IP address it was assigned, and may terminate the lease by releasing the IP address. The administrator can configure this lease time in the DHCP server.

Note: The DHCP Server can assign up to 253 IP Addresses to the LAN Clients. For

￿Addresses from 192.168.100.1 to 192.168.100.253. Please note that the addresses ending in 0 and 255 are reserved for other uses.example, if the router IP address is 192.168.100.254, the DHCP Server can assign IP

Select Misc → DHCP → DHCP Server to configure DHCP Server as explained below.
