The .de domain zone is one of the oldest and most popular national zones in the world, as it represents Germany in the global internet space. It is characterised by high user trust, strict technical requirements and specific legal rules established to ensure transparency, security and responsibility of domain owners. For this reason, many foreign companies and private individuals pay attention to .de domains, but do not always understand which norms regulate their use. To avoid mistakes and potential risks, it is important to understand the requirements imposed by German law and the domain zone administrator DENIC, and why these rules are mandatory even for registrants who do not reside in Germany.
