each of these in more detail.
Note: The Parani-MSP1000 will attempt to locate all this information every time it is turned on.
z IP address
A Static IP address acts as a “static” or permanent identification number. This number is assigned to
a computer to act as its location address on the network. Computers use these IP addresses to
identify and talk to each other on a network. Therefore, it is imperative that the selected IP address be
both unique and valid in a network environment.
Note: 192.168.1.x, 172.16.x.x and 10.x.x.x will never be assigned by and ISP (Internet Service
Provider). IP addresses using this form are considered private. Actual applications of the Parani-
MSp1000 may require access to public network, such as the Internet. If so, a valid public IP address
must be assigned to the user’s computer. A public IP address is usually purchased or leased from a
local ISP.
z Subnet mask
A subnet represents all the network hosts in one geographic location, such as a building or local area
network (LAN). The Parani-MSP1000 will use the subnet mask setting to verify the origin of all packets.
If the desired TCP/IP host specified in the packet is in the same geographic location (on the local
network segment) as defined by the subnet mask, the Parani-MSP1000 will establish a direct
connection. If the desired TCP/IP host specified in the packet is not identified as belonging on the local
network segment, a connection is established through the given default gateway.
z Default gateway
A gateway is a network point that acts as a portal to another network. This point is usually the
computer or computers that control traffic within a network or a local ISP (Internet service provider).
The Parani-MSP1000 uses the IP address of the default gateway computer to communicate with hosts
outside the local network environment. Refer to the network administrator for a valid gateway IP
address.
z Primary and Secondary DNS
The DNS (Domain Name System) server is used to locate and translate the correct IP address for a
requested web site address. A domain name is the web address (i.e. www.yahoo.com ) and is
usually easier to remember. The DNS server is the host that can translate such text-based domain
names into the numeric IP addresses for a TCP/IP connection.
The IP address of the DNS server must be able to access the host site with the provided domain
name. The Parani-MSP1000 provides the ability to configure the required IP addresses of both the
Primary and Secondary DNS servers addresses. (The secondary DNS server is specified for use
