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).

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 complex network (routing).

IP address

The IP address is the unique network-wide address of a network component in a network 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) 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 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.
