Having 100 % control over your domains is something very important and to be able to access and edit the DNS records for every single one of them is one of the things you have to look for when you search for a registration or a shared hosting provider. You may have heard of the so-called “name servers” that show where a domain address is hosted, but below them there is also a whole set 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 manages the emails for a specific domain address. These records are employed if you'd like to have your website with one company and the emails with another, as an illustration. You may also use a domain address for a non-website service or direct the traffic to it through special records. Some companies ask for an extra fee to give access to edit particular DNS records apart from the name servers.
