Why to use built-in DHCP server
Kerio Operator includes a built-in DHCP server. There are deployment scenarios in which it is useful to have a separate DHCP server for VoIP devices:
DHCP server is disabled in the default mode so that it does not collide with your existing DHCP server.
Configuring DHCP server
The built-in DHCP server must have a static IP address:
Kerio Operator will derive the conﬁguration of the DHCP server from the values you set for the interface’s IP address, network mask, and gateway. The DHCP server sends option 66 to Kerio Operator’s own address with every address lease.

Kerio Operator generates the range of IP addresses from a configured mask of a network interface and assigns these addresses automatically.
In this example, the range of IP addresses is 192.168.62.2 — 192.168.62.253.
