Having complete control of your domains is something rather important and to be able to access and edit the DNS records for any of them is one of the things you should look for when you search for a registration or a hosting provider. Maybe you have heard of the so-called “name servers” that show where a domain is hosted, but below them you will find a whole group of records, like 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 employed if you would like have your site with one company and the emails with another, for example. You can also use a domain for a non-website service or forward the traffic to it through special records. Some companies ask for an extra payment to provide access to edit certain DNS records besides the name servers.
