Having 100 % control of your domain names is something rather important and being able to access and edit the DNS records for each of them is one of the things you need to look for when you search for a registration or a shared hosting provider. Maybe you have heard of the so-called “name servers” that show where a domain address is hosted, but below them you will find a whole group 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 certain domain. These records are used if you'd like to have your web site with one provider and the emails with another, for example. You can also use a domain name for a non-website service or forward the traffic to it by using special records. Some companies ask for an additional fee to provide access to edit specific DNS records other than the name servers.
