Network terminology

General
The network switch ensures the correct
connections between the individual
components. In order to make this possible,
each device within a network must be
capable of being uniquely identified. Each
component therefore, is given its own
address, the so-called IP address. The IP
address is made up four blocks of numbers,
each of which can contain up to three digits.
These blocks of numbers are separated by a
full stop, e.g. 192.168.1.1.
Each of the individual blocks of digits can
have a value between 1 and 254. The values 0
and 255 are in part reserved for special
functions and therefore shouldn't be used. In
order to ensure a secure function of your
network, addresses from the pre-defined
range should be used, i.e.: fundamentally, the
first two blocks should be 192.168.xxx.xxx; the
third block can be selected from the values in
the range mentioned above (must be the
same for all the devices within a network
however) and the fourth block should be
used to differentiate each device,
e.g.: Symphony 192.168.001.001
NAS: 192.168.001.002
PC: 192.168.001.003
If you don't just want to use devices within
the local network but also music sources
from the Internet (Internet radio), the
Symphony must have the possibility of being
able to access the Internet. This can be
achieved, for example, through a router with
a connection to a DSL network. This router is
also a part of the network and will be
assigned its own IP address. In order to
enable this connection to the outside world
actually to be established, the Symphony
must additionally be informed of the address of
the router (Gateway).
It must be ensured that the first three blocks
of the Device IP, the Gateway IP and the DNS
1 are within the same address range, e.g.
192.168.0.xxx. The fourth block assigns a
unique address ("house number") to the
components in the local network. This
number may only occur once within the local
network. The Device IP mask should always
be given the address 255.255.255.0.
DNS
The Domain Name System (DNS) is one of
the most important services in the Internet.
Its main task is that of converting Internet
address like www.revox.de for example, into
its corresponding IP address. As a rule, the
router in home networks fulfils the function of
the DNS.
If you should decide for the manual network
configuration (without DHCP), just enter the
address of your router as the DNS address
during network configuration.
LAN
Local Area Network
Local cabled network
A LAN connection to the Symphony
is the
most fault-tolerant and problem free
transmission technology, which offers much
more security against eavesdropping than
WLANs or Power LANs.
Gateway
The computer or router in your network
through which the data traffic with the world
outside your network, i.e. the Internet is
handled.
