How DNS Works

The Domain Name System (DNS) is a hierarchical decentralized naming system used on the Internet. It translates domain names into IP addresses, enabling users to access websites using human-readable names instead of numerical IP addresses.

infoDNS Query Process:

  1. User enters a domain in their browser
  2. Browser queries the DNS resolver (usually ISP provided)
  3. Resolver queries root nameservers
  4. Root servers direct to TLD (Top Level Domain) servers
  5. TLD servers direct to authoritative nameservers for the domain
  6. Authoritative nameservers return the IP address
  7. Browser connects to the IP address and loads the website
