Having complete control over your domain names is something very crucial and to be able to access and edit the DNS records for each of them is among the things you should look for when you search for a registration or a cloud hosting provider. You might have heard about the so-called “name servers” that show where a domain is hosted, but below them there's a whole list 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 deals with the e-mails for a specific domain name. These records are employed if you want to have your web site with one company and the emails with another, for instance. Additionally you can use a domain for a non-website service or direct the traffic to it using special records. Some companies ask for an extra fee to grant access to edit particular DNS records other than the name servers.
