Having complete control over your domain names is something really important and to be able to access and edit the DNS records for each of them is one of the things you have to look for when you search for a registration or a web hosting provider. You might have heard of the so-called “name servers” that show where a domain 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 website, and the MX records, which show the server that manages the emails for a specific domain name. These records are employed if you'd like to have your site with one provider and the emails with another, for example. You could also use a domain address for a non-website service or direct the traffic to it through special records. A lot of companies ask for an additional fee to provide access to edit particular DNS records other than the name servers.
