Having complete control of your domain names is something quite necessary and to be able to access and edit the DNS records for any of them is one of the things you need to look for when you search for a registration or a shared hosting provider. Maybe you have heard of the so-called “name servers” that show where a domain address is hosted, but below them there is 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 e-mails for a certain domain. These records are employed if you would like have your web site with one company and the emails with another, for instance. You can also use a domain name for a non-website service or direct the traffic to it through special records. Many companies ask for an extra fee to provide access to edit particular DNS records besides the name servers.
