Having 100 % 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 one of the things you have to look for when you search for a registration or a website hosting provider. You might have heard of the so-called “name servers” that show where a domain address is hosted, but below them there is a whole list of records, like 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 e-mails for a particular domain. These records are used if you'd like to have your web site with one provider and the emails with another, for instance. You may 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 apart from the name servers.
