Having complete control over your domains is something rather crucial and to be able to access and edit the DNS records for each of them is one of the things you need 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 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 particular domain name. These records are used if you wish to have your web site with one provider and the e-mails with another, for example. You may also use a domain name for a non-website service or forward the traffic to it using special records. Many companies ask for an extra fee to grant access to edit particular DNS records apart from the name servers.
