Introduction to TCP/IP 77
Configuration Examples
pose are used. Within a LAN, you can use addresses which are not
unique world-wide:
IP enables the establishment of connections via one or more inter-
mediate stations. The decision whether to connect directly or indi-
rectly to the partner device depends on the network mask. The
network mask for a class C network is 255.255.255.0. If the IP
address of the partner device does not fit the network mask, the
connection is established via the default gateway. If a device
knows several data routes to different intermediate stations, one
speaks of a router.
The domain name system (DNS) resolves a plain text DNS name
into an IP address. The DNS is a hierarchically structured data-
base, distributed worldwide. A DNS server can supply information
on the names and IP addresses for which it is responsible. For all
other information, a DNS server contacts other DNS servers. For
the establishment of every connection from the workstation, it is
possible to give either an IP address, or a name that a DNS server
resolves into an IP address.
Note: For further explanations of technical terms, refer to the
Glossary on the CD supplied.
