DNS Understanding

DNS Management

Domain Registrars

  • domain registrar is normally the place where you purchased/obtained your domain
  • Your registrar could be a business that only does domain registration or even your web host itself.
  • whenever a request for a domain is made, the registrar is the first place that gets referenced for information.

Nameservers

  • they identify what set of servers any requests should reference in order to obtain a domain’s DNS records.
  • Your domain should have it’s nameservers pointed to wherever you are intending to manage your site’s DNS records.
