Domänenabstand

Domänenabstand refers to the minimum distance between two distinct domain names. This concept is primarily relevant in the context of Domain Name System (DNS) security and abuse prevention. It ensures that newly registered domain names are sufficiently separated from existing ones to mitigate various risks.

One of the main concerns addressed by domänenabstand is typo-squatting, where attackers register domain names that are similar to popular ones with slight misspellings, hoping to trick users into visiting their malicious sites. A sufficient domänenabstand makes it harder to register such close variations. Another related issue is brand infringement, where someone might register a domain that sounds similar to a well-known brand to mislead consumers.

The specific minimum distance can vary depending on the registrar, the registry operator for a top-level domain (TLD), and the policies in place. For instance, some TLDs might have rules preventing the registration of a domain name that differs from an existing one by only a single character or a common substitution. These rules are implemented to maintain the integrity of the DNS and protect users from potential fraud and phishing attempts. The concept is a proactive measure to foster a more secure online environment by introducing a buffer zone between potentially confusable domain names.
