Having 100 % control over your domain names is something rather crucial and to be able to access and edit the DNS records for each of them is one of the things you should look for when you search for a registration or a cloud web hosting provider. You may have heard about the so-called “name servers” that show where a domain is hosted, but below them there's 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 manages the e-mails for a specific domain address. These records are used if you want to have your website with one company and the e-mails with another, for example. Additionally you can use a domain name for a non-website service or direct the traffic to it using special records. Some companies ask for an extra fee to grant access to edit particular DNS records apart from the name servers.
