Network terminology glossary
DHCP
DHCP is an abbreviation for Dynamic Host
Configuration Protocol. DHCP is primarily
used to enable clients to fetch their network
configuration automatically from a server or
router. The Voxnet 219 supports DHCP.
DNS
The Domain Name System (DNS) is one of
the most important services in the Internet.
Its main task is that of converting Internet
addresses like www.revox.de for example,
into its corresponding IP address. As a rule,
the router in home networks also 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.
Ethernet network
A switch or a router with an integrated
switch ensures the correct connections of
the individual components within a network.
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 a 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.:
Voxnet 219 192.168.001.001
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 client
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. 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.
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.
IP address
Network address. Each device in the network
needs an IP address through which it can be
reached and uniquely identified. Network
addresses may not occur twice. This is
important if network addresses are assigned
manually. If addresses are issued in your
network through DHCP, you don't need to
worry about the IP address assignment as
the DHCL server automatically handles the
question of address management.
