DNS (Domain Name System) is used for translating human-readable domain names into numerical IP addresses, allowing users to access websites and other resources using easy-to-remember names instead of complex numerical addresses.
DNS (Domain Name System) is a hierarchical and decentralized naming system used for translating domain names into IP addresses. It is used to facilitate easier navigation on the internet by allowing users to enter familiar domain names instead of having to remember numerical IP addresses.
DNS (Domain Name System) is needed to enable users to access websites and online services using easy-to-remember domain names instead of having to use numerical IP addresses. It helps in managing and translating these domain names to their corresponding IP addresses, ensuring efficient and user-friendly internet navigation.
The four types of DNS servers are:
- DNS Resolver: Also known as a recursive resolver, it receives queries from client devices and interacts with other DNS servers to resolve the domain name to an IP address.
- Root Name Server: It is the first step in translating human-readable domain names into IP addresses, directing queries to the appropriate top-level domain (TLD) servers.
- TLD Name Server: It handles the top-level domains such as .com, .org, .net, and directs queries to the authoritative name servers for the specific domain.
- Authoritative Name Server: It provides the actual IP address for the domain name, containing the DNS records for the domain and responding with the correct IP address.
