Dhcp - Linksys BEFSR81 User Manual

DHCP

From the DHCP screen, shown in Figure 6-12, you can configure the Router as
a DHCP Server.
A Dynamic Host Configuration Protocol (DHCP) server automatically assigns
an IP address to each PC on your network for you. Unless you already have one,
it is highly recommended that you leave the Router enabled as a DHCP server.
DHCP Server DHCP is already enabled by factory default. If you already
have a DHCP server on your network, set the Router's DHCP option to
Disable. Click the Apply button. If you disable DHCP, remember to assign a
static IP address to the Router.
Starting IP Address Enter a value for the DHCP server to start with when
issuing IP addresses. This value must be 192.168.1.2 or greater, because the
Router's default IP address is 192.168.1.1.

Number of DHCP Users (Optional) Enter the maximum number of PCs that
you want the DHCP server to assign IP addresses to. This number cannot be
greater than 253. In order to determine the DHCP IP Address range, add the
last three digits of the starting IP address (e.g., 100) to the number of DHCP
users. By default, as shown in Figure 6-11, add 100 to 50 (number of DHCP
users), and the range is 192.168.1.100 to 192.168.1.149.
Client Lease Time The Client Lease Time is the amount of time a network
user will be allowed connection to the Router with their current dynamic IP
address. Enter the amount of time, in minutes, that the user will be "leased" this
dynamic IP address.
DNS The Domain Name System (DNS) is how the Internet translates domain
or website names into Internet addresses or URLs. Your ISP will provide you
with at least one DNS Server IP Address. If you wish to use another, type that
IP Address in one of these fields. You can type up to three DNS Server IP
Addresses here. The Router will use these for quicker access to functioning
DNS servers.
WINS The Windows Internet Naming Service (WINS) manages each PC's
interaction with the Internet. If you use a WINS server, enter that server's IP
Address here. Otherwise, leave this blank.
DHCP Clients Table Click the DHCP Clients Table button to show the cur-
rent DHCP Active IP Table, shown in Figure 6-13. (This data is stored in tem-
porary memory and changes periodically.)
