Having full control of your domain names is something very important and being able to access and edit the DNS records for every one of them is among the things you need to look for when you search for a registration or a cloud web hosting provider. You may have heard about the so-called “name servers” that show where a domain address is hosted, but below them there is also a whole group of records, for example the A record, which is the IP address of the server hosting the site, and the MX records, which show the server that deals with the emails for a particular domain. These records are used if you'd like to have your site with one provider and the emails with another, for example. Additionally you can use a domain name for a non-website service or forward the traffic to it through special records. A lot of companies ask for an additional fee to grant access to edit particular DNS records apart from the name servers.
