A website owner must register the domain name that they like before they can use. This ensures that they will be the only ones who are using that specific domain name. Registration of domain names are handled by domain name registrars accredited with the ICANN or the Internet Corporation for Assigned Names and Numbers. Usually, these domain name registrars also offer DNS hosting services, where they maintain DNS servers. 

Website owners are typically advised to have a separate DNS hosting provider from their domain name registrar even if they offer free DNS hosting services. A separate DNS hosting provider will ensure that their website will still be accessible and online if either the domain name registrar encounters problems or the separate DNS hosting company does.
