Having complete control over your domains is something really necessary and to be able to access and edit the DNS records for every single one of them is one of the things you need to look for when you search for a registration or a shared website 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 set 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 want to have your web site with one provider and the e-mails with another, for instance. You could also use a domain address for a non-website service or direct the traffic to it by using special records. Some companies ask for an additional fee to give access to edit particular DNS records besides the name servers.
