DHCP Server

You can operate the device as a DHCP server. This allows IPv4 addresses to be assigned
automatically to the connected devices. The IPv4 addresses are either distributed
dynamically from an address band you have specified or a specific IPv4 address (static) can
be assigned to a particular device.
On this page, specify the IPv4 address band from which the device receives any IPv4
address.
You configure the static assignment of the IPv4 addresses in "Static Leases".
Note
Maximum number of IP addresses
The maximum number of IPv4 addresses that the DHCP server supports is 100. In other
words, a total of 100 IPv4 addresses (dynamic + static).
With the static assignments, you can create a maximum of 20 entries.
218
then evaluated by the DHCP server.
