About this guide

A domain is quickly registered and activated in a short time – and usually everything works automatically in the long run without you having to worry about technical details.

In the background, however, various players are working with the help of a complex infrastructure to make your domain available worldwide - even if it changes malaysia phone data
server, provider or even domain owner. When you register a domain and use this infrastructure, you also enter into contractually regulated relationships with the players involved, and not just with your domain provider.

This guide provides you with comprehensive information about what you need to consider when registering domain names, but also when terminating a domain, changing provider or transferring domains to a new owner.

The Domain Name System (DNS)

In order to create order in the vastness of the Internet, all computers active on the Internet are assigned to so-called domains. The hierarchical Domain Name System ensures that these computers can be reached not only via their IP addresses, but also via unique host names. The name resolution of host names to IP addresses is handled by a globally distributed, decentralized system of name servers.

The structure of domain names

A complete Internet host name (Full Qualified Domain Name; FQDN) contains two pieces of information: the name of the domain to which a computer belongs and its actual host name, which distinguishes it from other computers in this domain. The domain identifier has two parts: On the far right of the FQDN is the so-called Top Level Domain (TLD), also known as the domain extension. To the left of this, before a dividing dot, is the Second Level Domain (SLD).

When you register a domain name, you choose both a suitable second level domain, such as your company name, and a suitable top level domain such as .de, .com, .berlin or .shop, for example (www.)companyname.shop.
