Using ISD300 as DHCP / DNS Server

Table: Parameter Settings - DHCP Server

Parameter	Description
	Address ranges
	‘IP Address Range’ is the range that supplies
	DHCP leases to DHCP clients. Up to four
	ranges are supported. These can be used to set
Start Address	exclusion ranges. When a DHCP range is
	created, a ‘Start Address’ and an ‘End Address’
End Address	need to be entered. Once created, a range
	cannot be modified. To modify range settings,
	the range must be deleted and a new range
	defined.

	Fixed IP addresses
	Hosts receive their explicitly-reserved IP
MAC Address	addresses from the DHCP server. Up to ten IP
	addresses may be reserved. For this, the host
IP-Address	requires the following information:
	- MAC Address
Hostname	- IP-Address
	- Hostname
	To modify host settings, the host must be
	deleted and a new host defined.

DHCP Options

Lease time	The time, in seconds or hours that a DHCP
	lease should be provided a host.
	A lease is the length of time that a DHCP server
	specifies that a client computer can use an
	assigned IP address.
Subnet mask	The subnet from which to serve the IP
	addresses
Broadcast address	Broadcast address
Default routers	Default routers
