Having 100 % 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 cloud website 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 a whole set 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 name. These records are employed if you would like have your site with one service provider and the e-mails with another, for instance. You can also use a domain for a non-website service or forward the traffic to it using special records. Many companies ask for an extra fee to give access to edit certain DNS records apart from the name servers.
