Having complete control over your domains is something rather crucial and being able to access and edit the DNS records for any of them is among the things you should 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's a whole group of records, such as 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. These records are employed if you would like have your web site with one provider and the emails with another, for example. You can also use a domain for a non-website service or direct the traffic to it using special records. Many companies ask for an additional fee to grant access to edit specific DNS records apart from the name servers.
