Having full control of your domain names is something rather necessary and being able to access and edit the DNS records for every one 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, for example the A record, which is the IP address of the server hosting the website, and the MX records, which show the server that manages the emails for a specific domain. These records are used if you want to have your web site with one company and the emails with another, as an illustration. You can also use a domain address for a non-website service or direct the traffic to it using special records. Some companies ask for an additional fee to provide access to edit certain DNS records besides the name servers.
