What is an IP address?

An IP address (Internet Protocol Address) is a numeric representation that uniquely identifies a particular interface in the network. Every device within a data network needs an address so that it can be uniquely identified. This applies to both the small home network as well as the Internet. This is the only way to ensure that the data stream arrives at the right device. When accessing a website, the browser always transmits the IP address of your device as well. Because only then does the web server know where to send the desired data packet. The abbreviation IP stands for Internet Protocol. The Internet Protocol is a widely used network standard - comparable to an international traffic language for computers. Like sentence grammar in German, English and French, the Internet Protocol prescribes the form in which information may be exchanged.

What does an IP address look like?

A well-known example of an IP address is This address is built according to the old standard IPv4: four numbers in the range 0 to 255, each number separated from the next one by one. However, this system can only represent a limited number of combinations.

Do I always have the same external IP address?

Usually not. As soon as your router connects to the Internet, it obtains an IP address, which is assigned dynamically by the Internet service provider (provider). As a result, the provider needs significantly fewer IP addresses than he has customers, because never all customers are online at the same time. As a rule, Internet connections are automatically disconnected from the provider shortly after 24 hours and the router gets a new IP address.
