Having full control over your domains is something very necessary and being able to access and edit the DNS records for every one of them is among the things you should look for when you search for a registration or a website hosting provider. You may have heard about the so-called “name servers” that show where a domain is hosted, but below them you will find a whole set 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 handles the e-mails for a particular domain name. These records are employed if you'd like to have your website with one service provider and the emails with another, for example. Additionally you can use a domain name for a non-website service or direct the traffic to it by using special records. Some companies ask for an additional fee to grant access to edit particular DNS records other than the name servers.
