A domain is used to reach websites. You can of course just enter the IP address like 175.183.19.94 but this is a bit difficult to remember in the long run. That is why domains like www.amazon.de were introduced, which make it easier to use.
A domain consists of three parts. Firstly, first-level such as .de .com or .fr and many more. So the ending. On the other hand there is the middle part, for example Amazon, which is the name of what is called. Last but not least, in the third level, which does not always have to be the case, the sub-page such as partnernet.amazon.de can be found
Furthermore, there have recently been many other endings such as .tips, .blog, .berlin and many more, which are becoming more and more numerous. A domain can be booked with any provider and is managed by a central domain office in Germany (DENIC).
