Network Terminology

The Switch ensures that the individual components within a network are
connected correctly. This is only possible if it can identify each device within
the network unambiguously; this is the reason why every component is
assigned a form of "house number" (IP address). The IP address consists of
four number blocks each containing three digits separated by dots (e.g.
192.168.1.1).
Each of the individual number blocks may contain values between 1 and 254
(the values 0 and 255 are reserved for certain special functions, and should
therefore not be used). However, if the network is to operate reliably, the
network owner should only select addresses designed for home network use
- i.e.: the first two number blocks should always be 192.168.xxx.xxx; the
third block can be selected without restriction within the above limits (but
should be the same for all devices on the network), and the fourth block
must distinguish each device uniquely (e.g.: SDV 3100 HV 192.168.001.001,
NAS: 192.186.001.002, PC: 192.168.001.003, ...).
If this local network is to include Internet music sources (Internet radio) as
well as physical devices, then the SDV 3100 HV must have access to the
Internet. This facility is provided by a device such as a router with connection
to the DSL network. This router is also a constituent part of the network, and
is assigned its own IP address. The SDV 3100 HV must also be informed of
the address of the router (Gateway) to enable it to gain access to the outside
world.
 Please ensure that the first three blocks of the Device IP, Gateway IP and
DNS 1 share the same address space (e.g. 192.168.0.xxx). The fourth block
assigns a unique address (house number) to the components in the local
network. This number must not be present more than once in the local
network.
The Device IP mask should always be assigned the address 255.255.255.0.
The Domain Name System (DNS) is one of the most important services on the
Internet. Its primary task is to convert "Internet addresses", such as
www.taelektroakustik.de, into the associated IP address. In most home
networks the router carries out the DNS function.
If you decide to configure your network manually (without DHCP), then
simply enter the address of your router as the DNS address when configuring
the network.
Wired network. Interference-free network technology, with the drawback of
having to deploy a network cable.
The computer or router in your network which is responsible for managing
data traffic between your home network and the outside world (i.e. the
Internet).
Network device which obtains data from the network, decodes it and
converts it into, for example, analogue music signals which can then be
reproduced via an amplifier and loudspeakers. Streaming Clients also
contain functions for displaying media content, and for navigating on the
Internet or servers.
DHCP is an abbreviation of Dynamic Host Configuration Protocol. The
primary purpose of DHCP is to enable Clients to obtain your network
configuration automatically from a server or router.
Network address. Each device in the network requires an IP address at which
it can be accessed, and by which it is unambiguously identifiable. No
individual network address may be present more than once. This is
important if you are entering network addresses manually. If the addresses
in your network are assigned by DHCP, you do not need to worry about IP
addresses at all, as the DHCP server manages the addresses automatically
without your intervention.
