Having total control over your domain names is something very necessary and to be able to access and edit the DNS records for every one of them is among the things you have to look for when you search for a registration or a cloud hosting provider. You might have heard of the so-called “name servers” that show where a domain address is hosted, but below them there's 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 e-mails for a certain domain name. These records are used if you want to have your site with one company and the emails with another, for example. Additionally you can use a domain name 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 certain DNS records other than the name servers.
