Having total control of your domains is something quite important and to be able to access and edit the DNS records for any of them is among the things you have to look for when you search for a registration or a shared hosting provider. You may have heard about the so-called “name servers” that show where a domain name is hosted, but below them you will find a whole group 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 handles the emails for a certain domain address. These records are used if you would like have your web site with one provider and the e-mails with another, for instance. Additionally you can use a domain for a non-website service or forward the traffic to it by using special records. Many companies ask for an extra payment to provide access to edit certain DNS records apart from the name servers.
