Specifications
Changing settings for the IPv4 DHCP server is optional. The default selections are almost always sufficient.
DHCP Server: (Default: Enabled) When the DHCP server is enabled, users of your network will be able to automatically connect to the Internet without any special
configuration. It is recommended that you leave this enabled. Disabling the DHCP server is only recommended if you have another DHCP server on your network and
it is configured properly.
Range Start and Range End: These designate the range of values in the reserved pool of IP addresses for the DHCP server. Values within this range will be given to any
DHCP enabled computers on your network. The default values are almost always sufficient (default: 72 to 200, as in 192.168.0.72 to 192.168.0.200).
Example: The router uses an IP address of 192.168.0.1 for its primary network by default. A computer designated as a Web server has a
static IP address of 192.168.0.3. Another computer is designated as an FTP server with a static IP address of 192.168.0.4. The starting
IP address for the DHCP server needs to be 192.168.0.5 or higher.
Lease Time: [Default: 720 minutes (12 hours)] The lease time specifies how long DHCP-enabled computers will wait before requesting a new DHCP lease. Smaller values
are better suited to busy environments.
Custom Options: Input a custom DHCP option by first clicking the Custom Options field to enable it and then clicking “Add” at the top of the table that appears. There
are close to 200 possible DHCP options available. One of the more common uses is to assign a VoIP phone server using option 66 (Server name).
Option: Select an option from the dropdown list or manually enter the number of an option. A complete list of options is available from IANA.
Value: Generally this field should be a string, IP address, or numeric value. Some fields can accept both IP addresses and hostnames – in these cases you may
