Having total control over your domains is something really crucial and being able to access and edit the DNS records for every single one of them is one of the things you should look for when you search for a registration or a shared website hosting provider. You may have heard about the so-called “name servers” that show where a domain address is hosted, but below them there is a whole list 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 specific domain address. These records are employed if you want to have your web site with one provider and the e-mails with another, for instance. Additionally you can use a domain address for a non-website service or forward the traffic to it through special records. Some companies ask for an additional payment to give access to edit certain DNS records other than the name servers.
