DHCP Function
DHCP (Dynamic Host Configuration Protocol) is a protocol that
lets network administrators manage centrally and automate the
assignment of IP (Internet Protocol) configurations on a com-
puter network. When using the internet’s set of protocols (TCP/
IP), in order for a computer system to communicate to another
computer system, it needs a unique IP address. Without DHCP,
the IP address must be entered manually at each computer sys-
tem. DHCP lets a network administrator supervise and distribute
IP addresses from a central point. The purpose of DHCP is to
provide the automatic (dynamic) allocation of IP client configu-
rations for a specific time period (called a lease period) and to
eliminate the work necessary to administer a large IP network.

Local IP address
If you intend to set up your client computers manually (no
DHCP), make sure that the assigned IP address is in the same
range as the default router address and that it is unique to your
private network. However, it is highly recommend to use DHCP
if that option is available on your network. An IP address alloca-
tion scheme will reduce the time it takes to set-up client com-
puters and eliminate the possibilities of administrative errors
and duplicate addresses. To manually configure the IP address
of the controller, move the cursor bar to Local IP address item,
then reassign the static IP address of the controller.
• Gateway IP address
A gateway is a node (a router) on a TCP/IP network that serves
as an access point to another network. A default gateway is the
node on the computer network that the network software uses
when an IP address does not match any other routes in the
routing table.
• Subnet Mask
A Subnet mask is a 32-bit number that masks an IP address,
and divides the IP address into network address and host ad-
dress.
• HTTP Port Number
To manually configure the “HTTP Port Number” of the controller,
move the cursor bar to “HTTP Port Number” item, then reassign
