How do DNS records work?

DNS records resemble the instructions that are stored in root DNS servers’ zone entries. DNS records map the DNS setup of each website.

On the internet, there are several varieties of DNS records. However, these are the most typical DNS record types that may be found on any website.

  • A record – Points website name to IPV4 address
  • AAAA –  Points hostname to IPV6 address
  • NS  –  specifies the authoritative nameservers
  • MX –  responsible for directing an email to a mail server.
  • PTR –  Used for reverse lookups
  • CNAME – redirects one domain to another. For example, even if you just type coolicehost.com in the web browser, you will be redirected to www.coolicehost.com, which is the DNS record behind that configuration.
