Having full control over your domain names is something very important and being able to access and edit the DNS records for every single one of them is among the things you should look for when you search for a registration or a shared hosting provider. You might have heard about the so-called “name servers” that show where a domain is hosted, but below them there is a whole list 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 manages the e-mails for a certain domain. These records are used if you wish to have your site with one provider and the emails with another, for instance. You may also use a domain address for a non-website service or forward the traffic to it through special records. Many companies ask for an additional payment to give access to edit certain DNS records other than the name servers.
