DSL-500 ADSL Router User's Guide The Dynamic Host Configuration Protocol (DHCP) allows the Router to dynamically assign IP addresses to network devices. Dynamic IP assignment eliminates the need for the network administrator to maintain and monitor IP address assignments and simplifies IP use because IP address are automatically and dynamically assigned when a computer is powered-on. Important Note: If you use DHCP to set your local IP addresses, the software IP settings of all stations on the network will need to be manually configured to 0.0.0.0., or, as in the case of Windows 95 users, the "Obtain an IP address automatically" option under TCP/IP will have to be selected. Start IP Address This is the base (starting) address for the IP pool of unassigned IP addresses. End IP Address This is the last address of the contiguous IP address range to be used by the Router for DHCP function. Netmask This mask informs the client how the destination IP address is to be divided into network, subnet, and host parts. Default Gateway This specifies the Gateway IP Address that will be assigned to and used by the DHCP clients. Leased Time The specified amount of time (in seconds) a client can lease an IP address, from the dynamically allocated IP pool. A value of 4123456789 means the lease is permanent. DNS Server IP Domain Name Service (DNS) servers are used on the Internet to match the Uniform Resource Locator (URL) for a website to its Internet IP address. For example, the URL: www.cnn.com, is a pseudonym for the IP address: 207.25.71.25. DNS entries allow users to access resources using URLs instead of IP addresses. You may enter any Internet DNS server IP address available through the WAN connection. Your ISP should provide this address. (Note that without a DNS server IP, internet sites will only be available using IP addresses and will not be available using URLs.) State This toggles Disable and Enable for DHCP function. 16
