Having 100 % control over your domain names is something rather crucial and to be able to access and edit the DNS records for any of them is among the things you have to look for when you search for a registration or a cloud hosting provider. You might have heard about the so-called “name servers” that show where a domain is hosted, but below them there's a whole set of records, like the A record, which is the IP address of the server hosting the website, and the MX records, which show the server that handles the e-mails for a particular domain. These records are used if you wish to have your site with one company and the emails with another, for example. You could also use a domain name for a non-website service or direct the traffic to it through special records. A lot of companies ask for an extra payment to provide access to edit certain DNS records apart from the name servers.
