Domain Name System (DNS) is a hierarchical naming system for computers, services, and other devices on the Internet. DNS is a distributed database that stores the corresponding addresses of domain names and their aliases.

DNS is divided into levels, each of which provides increased functionality. The three primary DNS layers are the Domain Name System (DNS), the Domain Name System Security Extensions (DNSSEC), and the Internet Protocol (IP) Address Domain Name System (IDNS).

The Domain Name System (DNS) is the most fundamental DNS layer and is responsible for translating human-readable domain names into IP addresses. DNS servers use a hierarchical naming system to organize the database of addresses.

Each domain name is associated with a unique DNS server.

The Domain Name System Security Extensions (DNSSEC) provide enhanced security for domain names. DNSSEC allows administrators to sign and encrypt DNS records to ensure their authenticity.

The signing process creates a digital signature for each DNS record. The encryption process uses a cryptographic algorithm to create a tamper-proof digital signature for each DNS record.

The Internet Protocol (IP) Address Domain Name System (IDNS) provides a mapping between human-readable domain names and IP addresses. IDNS allows users to resolve domain names by querying DNS servers for the IP address associated with the domain name.
