Having 100 % control of your domain names is something really important and being able to access and edit the DNS records for every single one of them is among the things you have to look for when you search for a registration or a web hosting provider. You might have heard about the so-called “name servers” that show where a domain name is hosted, but below them there is a whole list 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 deals with the emails for a particular domain name. These records are employed if you'd like to have your web site with one service provider and the emails with another, for instance. You could also use a domain name for a non-website service or direct the traffic to it through special records. Many companies ask for an additional fee to grant access to edit specific DNS records besides the name servers.
