NetScan and TCP/IP Addressing
Protocol
The NetScan uses TCP/IP (Transport Control Protocol/Internet Protocol) for communications over the
ethernet. You can access NetScan devices from virtually anywhere in the world since the World Wide Web
uses this same protocol.
ethernet. You can access NetScan devices from virtually anywhere in the world since the World Wide Web
uses this same protocol.
TCP/IP addressing consists of three parameters: the IP address, the Sub-net Mask, and the Gateway
Address. Each of these parameters consists of four different numbers which range from 0 to 255. The
numbers are typically represented in a dotted decimal format, for example: 192.88.247.11.

IP Address
The IP (Internet Protocol) is a device address that is unique to one specific device located on the network.
A device’s IP address can not be shared by any other device on the network. The only restrictions on the IP
address are:
1) the first number must be between 127 and 255
2) the last number must be between 1 and 254.

Sub-net Mask
The Sub-net Mask determines how many addresses are on the network. Note that Class C networks consist
of up to 256 addresses; and are quite common. For a Class C Network the Sub-net Mask would be
255.255.255.0. All computers on the network must have the same subnet mask.

Gateway Address
A gateway address is needed to a access a device (gateway, or router) that can route traffic from one
network to another. The gateway address is the actual address of the gateway (router) device.
