Having full control over your domain names is something very important and being able to access and edit the DNS records for every one of them is among the things you should look for when you search for a registration or a web hosting provider. You may have heard of the so-called “name servers” that show where a domain name is hosted, but below them there's a whole group 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 deals with the emails for a certain domain name. These records are employed if you'd like to have your website with one service provider 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 payment to provide access to edit particular DNS records besides the name servers.
