The following options can be configured for a DHCP server:
General Parameters
Name
A symbolic name for the server. Used as an interface reference but also
used as a reference in log messages.
Interface Filter

requests. This can be a single interface or a group of interfaces.
IP Address Pool
An IP range, group or network that the DHCP server will use as an IP
address pool for handing out DHCP leases.
Netmask
The netmask which will be sent to DHCP clients.
Optional Parameters
Default GW
This specifies what IP should be sent to the client for use as
the default gateway (the router to which the client connects).

domain.com.
Lease Time
The time, in seconds, that a DHCP lease is provided. After
this time the DHCP client must renew the lease.
Primary/Secondary DNS

are used in Microsoft environments which uses the NetBIOS
Name Servers (NBNS) to assign IP addresses to NetBIOS

This is usually a TFTP server.
