DNS (Domain Name System)

A system that keeps the information about Internet domains, with its key function being to provide the IP address of a node or other resource upon receiving its full domain name. The system consists of multiple servers and has a distributed hierarchical architecture. In order to minimize DNS hacking attack risks and ensure the integrity and authenticity of data kept by DNS, its servers use built-in protection and security features, such as DNSSEC, TSIG, DANE, and others.
