DNSbasiertes

DNSbasiertes refers to systems or services that rely on the Domain Name System (DNS) for their operation. DNS itself is a hierarchical and decentralized naming system for computers, services, or any resource connected to the Internet or a private network. It translates human-readable domain names, such as www.example.com, into machine-readable IP addresses, like 192.0.2.1, which computers use to identify each other.

When something is described as DNSbasiertes, it means that its functionality is intrinsically linked to the DNS resolution process. For instance, a DNSbasiertes advertising system might deliver ads based on the domain name a user is trying to access. Similarly, DNSbasiertes security services could block access to malicious websites by preventing their domain names from resolving to IP addresses. This can involve techniques like DNS sinkholing, where queries for specific domains are redirected to a controlled server. Content delivery networks (CDNs) often employ DNSbasiertes routing to direct users to the geographically closest server for faster content delivery. The fundamental principle is that the domain name is the key identifier that triggers a specific action or provides specific information within the system.
