Having complete control over your domain names is something rather important and to be 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 shared website hosting provider. You may have heard of the so-called “name servers” that show where a domain name is hosted, but below them there is also 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 deals with the e-mails for a specific domain address. These records are used if you'd like to have your website with one service provider and the emails with another, for instance. You may also use a domain name for a non-website service or forward the traffic to it through special records. A lot of companies ask for an additional fee to give access to edit certain DNS records besides the name servers.
