Introduction to TCP/IP

In a single LAN it is possible to use various protocols for the transmission of data.
The connection between a workstation computer and the OpenCom 510 runs via
the IP protocol (also named TCP/IP) used on the Internet. IP can be used together
with other protocols (e.g. NetBEUI, AppleTalk or IPX/SPX) on the same network.
Every device participating in data transmission using IP requires a unique IP
address. An IP address consists of four groups of digits from 0 to 255, each sepa-
rated by a full stop. The supplementary protocols DHCP and PPP automatically
assign IP addresses to devices. Class C networks normally use IP addresses in
which the first three numbers are the same and the last number is uniquely
assigned to a specific device in the LAN. On the Internet, unique addresses
assigned by a special organisation created for this purpose are used. Within a LAN,
you can use addresses which are not unique world-wide:
IP Range
192.168.0.0-
192.168.255.255
172.16.0.0-172.31.255.255
10.0.0.0-10.255.255.255
