Having total control of your domains is something rather important and being able to access and edit the DNS records for each of them is among the things you need to look for when you search for a registration or a website hosting provider. Perhaps you have heard of the so-called “name servers” that show where a domain address is hosted, but below them there's a whole set of records, such as 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 emails for a certain domain address. These records are used if you wish to have your web site with one company and the e-mails with another, as an illustration. You could also use a domain name for a non-website service or forward the traffic to it by using special records. Many companies ask for an extra fee to provide access to edit specific DNS records apart from the name servers.
