Who Is Responsible for DNS Server?
When it comes to the Domain Name System (DNS), there are several entities involved in its operation. Let’s take a closer look at the key players and their responsibilities.
The Internet Corporation for Assigned Names and Numbers (ICANN)
The ICANN is a non-profit organization responsible for coordinating and maintaining the overall architecture of the DNS. They oversee the allocation of IP addresses, management of top-level domains (TLDs), and ensure the stability and security of the DNS.
Internet Assigned Numbers Authority (IANA)
The IANA is a department within ICANN that manages various technical aspects of the DNS, including root zone management. They oversee the delegation of TLDs to different registry operators, ensuring that domain names are properly distributed.
Registry operators are responsible for managing specific TLDs. For example, Verisign operates the .com and .net TLDs. They maintain a registry database containing information about registered domain names within their TLD and provide authoritative answers to DNS queries for those domains.
Registrars act as intermediaries between individuals or organizations looking to register domain names and registry operators. They allow users to search for available domain names, register them, and manage their DNS settings.
DNS resolvers play a crucial role in translating human-readable domain names into IP addresses. When you type a URL into your web browser, your computer sends a DNS query to a resolver, which then contacts authoritative name servers to find the IP address associated with that domain name.
Authoritative Name Servers
Authoritative name servers store specific DNS records for a domain. When a resolver requests information about a domain, the authoritative name servers respond with the correct IP address or other DNS records, such as MX records for email.
The responsibility for DNS server management is distributed among multiple entities. ICANN oversees the overall coordination and stability of the DNS, while IANA manages technical aspects and TLD delegation. Registry operators manage specific TLDs, registrars facilitate domain registration, DNS resolvers translate domain names into IP addresses, and authoritative name servers store and provide DNS records for domains.
Understanding the roles of these entities helps ensure the smooth functioning of the DNS system, enabling us to navigate the internet seamlessly.
