Understanding how basic DNS system works is helpful when troubleshooting your site's issues or deciding how to configure your domain

There are some important points that need to be understood

DNS – domain name system used to translate host names to IP address
DNS zone – is a text record that contains IP address to host name translations
address-to-name translation – a line of text in the DNS zone that tells at what IP address and a host is located

  1. A DNS zone is the record that contains all IP address-to-name translations.
  2. Name servers are where DNZ zone is stored.

Normally, when you register a domain you have two options:

  1. Point your domain to your web hosting company's name servers and let them manage the zone for you
  2. Use your domain registrar and create a zone there and manage everything from the registrar's end
