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 T-Comfort 930 DSL 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 separated 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:
