Internet
The Internet is a wide-area network (

WAN

) linking several million users around the

world. A number of

Protocols

have been created for exchanging data, and these are

known collectively as

TCP/IP

. All participants on the Internet can be identified by an

IP

address

. Servers are addressed by

Domain names

(e.g. siemens.com). Domain names

are assigned to IP addresses by the Domain Name Service (

DNS

).

These are some of the main Internet services:

u

Electronic mail (e-mail)

u

The World Wide Web (WWW)

u

File transfer (FTP)

u

Discussion forums (Usenet / Newsgroups)

Internet service provider
An Internet service provider offers access to the

Internet

for a fee.

Internet telephony
Transmission of voice via the

Internet

(Voice over

IP

).

IP
Internet protocol
The IP

Protocol

is one of the

TCP/IP

protocols. It is responsible for addressing parties in a

network using

IP addresses

and routes data from the sender to the recipient. It decides

the paths along which the data packets travel from the sender to the recipient in a com-
plex network (routing).

IP address
The IP address is the unique network-wide address of a network component in a net-
work based on the

TCP/IP

protocols (e.g. in a local area network (

LAN

) or on the

Inter-

net

). The IP address has four parts (each with up to three-position digit sequences) sep-

arated by full stops (e.g. 192.168.1.1). The IP address comprises the network number
and the computer number. Depending on the

Subnet mask

, one, two or three parts

form the network number; the remainder form the computer number. You can find out
the IP address of your PC using the ipconfig command.
IP addresses can be assigned manually (see

Static IP address

) or automatically (see

Dynamic IP address

).

On the Internet

Domain names

are normally used instead of the IP addresses. The

DNS

is used to assign domain names to IP addresses.
The Gigaset SX763 WLAN dsl has a

Private IP address

and a

Public IP address

.
