Having total control of your domains is something rather necessary and being able to access and edit the DNS records for every single one of them is among the things you have to look for when you search for a registration or a website hosting provider. Perhaps you have heard of the so-called “name servers” that show where a domain is hosted, but below them you will find a whole group of records, like the A record, which is the IP address of the server hosting the website, and the MX records, which show the server that deals with the emails for a specific domain. These records are used if you'd like to have your web site with one provider and the emails with another, for instance. You may also use a domain address for a non-website service or forward the traffic to it by using special records. Many companies ask for an additional payment to give access to edit particular DNS records apart from the name servers.
