Having full control of your domains is something really necessary and to be able to access and edit the DNS records for every single one of them is among 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 name is hosted, but below them you will find 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 specific domain. These records are employed if you'd like to have your site with one provider and the emails with another, for instance. You may also use a domain for a non-website service or direct the traffic to it by using special records. Many companies ask for an extra fee to grant access to edit certain DNS records apart from the name servers.
