Having full control over your domain names is something quite necessary and being able to access and edit the DNS records for every single one of them is one of the things you should 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 address is hosted, but below them there is also a whole list of records, like the A record, which is the IP address of the server hosting the site, and the MX records, which show the server that handles the emails for a specific domain name. These records are used if you'd like to have your site with one company and the emails with another, for instance. You can also use a domain address for a non-website service or forward the traffic to it through special records. A lot of companies ask for an extra fee to provide access to edit certain DNS records other than the name servers.
