Opencom 510 In A Serverless Lan - Aastra OpenCom 510 User Manual

Configuration Examples
IP enables the establishment of connections via one or more intermediate sta-
tions. The decision whether to connect directly or indirectly 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 database, 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.

OpenCom 510 in a Serverless LAN

In a peer-to-peer network, the workstations are connected to one another via
network cables. In many networks, the cables run in the form of a star from a
central hub or switch. Such networks do not require special servers. This configu-
ration example is also valid for a LAN with a server using a protocol other than IP
(e.g. AppleTalk or IPX/SPX).
