Having full control of your domains is something very 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 shared website hosting provider. You might have heard of the so-called “name servers” that show where a domain address is hosted, but below them you will find a whole set 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 deals with the emails for a particular domain name. These records are employed if you'd like to have your website with one service provider and the e-mails with another, for example. Additionally you can use a domain address for a non-website service or forward the traffic to it by using special records. A lot of companies ask for an additional fee to give access to edit specific DNS records other than the name servers.
