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

).
