Having full control of your domain names is something really crucial and being 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. Perhaps you have heard about the so-called “name servers” that show where a domain name 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 handles the e-mails for a certain domain. These records are used if you would like have your site with one service provider and the e-mails with another, for instance. Additionally you can use a domain name for a non-website service or forward the traffic to it using special records. A lot of companies ask for an additional fee to give access to edit specific DNS records apart from the name servers.
