Having full control of your domains is something rather necessary 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 web hosting provider. Perhaps you have heard of the so-called “name servers” that show where a domain name is hosted, but below them there is a whole set of records, such as the A record, which is the IP address of the server hosting the site, and the MX records, which show the server that handles the emails for a specific domain address. These records are used if you wish to have your website with one service provider and the emails with another, for instance. You may also use a domain name for a non-website service or direct the traffic to it by using special records. Some companies ask for an extra fee to grant access to edit certain DNS records besides the name servers.
