Having full control of your domain names is something very necessary and being 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 web hosting provider. Maybe you have heard about the so-called “name servers” that show where a domain address is hosted, but below them there is a whole list 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 e-mails for a particular domain address. These records are used if you want to have your site with one company and the e-mails with another, for example. You can also use a domain name 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 particular DNS records apart from the name servers.
