General
An overview of relevant terms when using the device in a
network can be found below.
Parameter Setting
IP address An IP address is the unique address of a
network device within a network.
This address may only appear once
within a network. Certain IP address
ranges are reserved for public networks
(e.g. the Internet).
Subnet
mask A subnet mask is a bit mask used for
making decisions and assignments
during routing.
255.255.255.0 is the standard subnet
mask in home networks.
Gateway A gateway is a network device which
allows all other network devices to
access the Internet.
This can be the computer connected to
the DSL modem or – usually – the router
or access point within the network.
Name
server The name server is responsible for
assigning a unique IP address to a web
address or URL (e.g. www.google.de).
Also known as DNS (Domain Name
Server).
When a domain name is entered into a
browser, the DNS searches for the
corresponding IP address of the server
and forwards the query on.
The IP of the provider’s DNS can be
entered here. However, it is often
sufficient to select the IP of the gateway.
This then forwards the queries
independently to the provider DNS.
DHCP The DHCP server automatically assigns
the IP address, subnet mask, gateway
and name server to a network device.
DHCPs are available in current routers.
The DHCP service must be specially set
and activated (see the corresponding
manual for more information).
Note:
When using fixed IP addresses and a
DHCP server, make sure that the fixed IP
addresses are outside the address range
assigned by DHCP. Otherwise, problems
could occur.
Port A port is an interface used for
communication by different programs.
Certain ports are fixed (21: Telnet, 23:
FTP), whilst others can be freely
selected. Ports are important for different
applications (e.g. external access to the
device over a browser).
MAC
address The MAC address (Media Access
Control or Ethernet ID) is the specific
hardware address of the network
adapter.
This is used for the unique identification
of the device in a computer network.
