and the Forum 523/524 runs via the IP protocol (also named TCP/
IP) used on the Internet. IP can be used together with other pro-

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 pur-
