IP address
An IP address is the unique network-wide address of a network component in a network
based on the
TCP/IP
consists of four parts (each of up to three-figure strings of digits from 0–255) that are
separated from one another by full stops (e.g. 192.168.2.1). The IP address is made up
of the network number and the number of the network component. Depending on the
Subnet
mask, one, two or three parts form the network number, the remainder form the
network component number. You can find out the IP address of your PC using the
ipconfig command.
There are two different types of IP address:
u
Private IP address:
IP address of a network component within a local network.
u
Public IP address:
IP address that uses a network component for accessing the Internet.
IP addresses can be assigned manually or automatically:
u
Static IP address:
The IP address is manually assigned to a network component and never changes.
u
Dynamic IP address:
The IP address is assigned to the network component by a DHCP server. The IP
address of this network component can change each time it registers with a network
or at specific time intervals.
On the Internet, domain names are normally used instead of the IP addresses. DNS is
used to assign domain names to IP addresses.
IPTV
Internet Protocol Television. You receive your provider's television service via the DSL
connection. To do this, you require an IPTV-capable set-top box and the configuration
data of your IPTV provider.
ISP
Internet Service Provider. See Provider.
LAN
Local Area Network, local network. A local network links network components so that
they can exchange data and share resources. The physical range is restricted to a partic-
ular area (a site). A local network can be connected to other local networks or a wide-
area network (WAN) such as the Internet.
LED
Light Emitting Diode. An LED is an electronic component (semi-conductor) that gener-
ates light at low power consumption. LEDs are often used as signal lights for display and
UI elements.
