The Root Server System (RSS) is a critical infrastructure of the global DNS that operates as the foundation for translating domain names into IP addresses. It consists of 13 logical root servers, identified by letters (A through M), managed by independent organizations distributed across the world. These root servers respond to DNS queries by directing them to authoritative name servers, playing an essential role in ensuring the stability, security, and resilience of the Internet's addressing system. The RSS is overseen by the RSSAC under ICANN, which provides guidance to maintain its effective operation.
