Domain Name System (DNS) is a hierarchical naming system for computers, established in the early 1980s. A DNS server is a special-purpose computer system that provides the resolution of domain names to IP addresses.

In theory, any computer with an IP address can act as a DNS server, but the most common implementation of DNS is for use by the Internet Corporation for Assigned Names and Numbers (ICANN) in their root name servers.

Domain names are composed of two parts: the host part (ex. www.example.com) and the domain part (ex. com). The host part is the physical address of the computer hosting the website, while the domain part is the name of the company or organization that owns the website. The DNS resolves the host part (www.

example.com) to an IP address (144.193.68.10) and the domain part (example.com) to the corresponding A record in the DNS server’s database.

The conclusion to this article is that domain name and DNS are the same thing.
