DHCP, DNS and Time
Dlink DRO-210i User Guide 19
Default Gateway Enter the default gateway IP address that the router will assign to the
hosts on the network.
Lease Time (sec) Enter the length of time any host on the network can keep its DHCP
settings assigned by the router. If the lease expires while the host is
logged on, then that host will request for a new set of DHCP settings. The
default Lease Time is 60 seconds.
Auto Configuration Select Enable to enable the DNS Proxy in the router (the router acts as a
DNS server). In this case, the router gets the DNS IP manually or from
ISP. When Disable is selected, the network settings entered by the
administrator will be assigned to hosts on the network. In this case the
DNS server IP addresses should be specified.
Domain Name Enter a domain name the router can assign to hosts on the network. This
suffix will then be automatically added to URL requests for access to your
ISP's servers.
Primary DNS
Server
Enter the IP address of a DNS server on the Internet that provides the
service of converting text URLs into IP address for sites on the Internet.
Secondary DNS
Server (optional)
Enter the IP address of a secondary DNS server that is be used when
there is a problem with the Primary DNS Server. Select the Disable
checkbox to disable Secondary DNS.
After entering all the information press the Apply button. The DHCP Client Table will
list the client hosts (to which IP addresses have been assigned) with their Host Name, IP
Address, MAC Address, and Lease Time values.
Any IP address in the DHCP server range may be assigned as a static IP to some PC in
the network. When DHCP Server tries to assign this IP address to ano ther client, the
client will send a DECLINE message to the server. This is shown in the DHCP Client
Table as DECLINED in host name, with MAC Address of zero and lease time of one
hour.
DHCP Static Mapping (or DHCP Reservation) is a method of assigning static IP address
to a defined MAC Address. System administrators can use this feature to configure a
static IP address for some of the systems in the LAN. These IP addresses however need
to fall within the DHCP server configured IP Address Range.
