IP address
The IP address is the unique network-wide address of a network component in a net-
work based on the
TCP/IP protocol (e.g. in a local network ( LAN ) or on the Internet ). The
IP address has four parts (decimal numbers) separated 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
forms 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. DNS is
used to assign domain names to IP addresses.
The Gigaset SE551 WLAN dsl/cable has a
Private IP address and a Public IP address .
