Applications

devices attached to the DHCP Server to be set. The number of addresses to be assigned must also be specified to a maximum of 253.

With the DHCP Services and IP Address Pool defined, devices may be attached to the network (up to the maximum specified) and they will be automatically configured.

When setting up a router as a DHCP server that will have both a DNS server on the internal network and a remote connection to another DNS server (for example, through an ISP), then the local DNS server should be set as the primary DNS and the external DNS server as the secondary DNS.
