Having total control over your domain names is something rather crucial and to be able to access and edit the DNS records for any of them is one of the things you have to look for when you search for a registration or a hosting provider. Maybe you have heard of the so-called “name servers” that show where a domain name is hosted, but below them there is a whole list 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 deals with the emails for a certain domain name. These records are used if you wish to have your site with one service provider and the emails with another, for example. You could also 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 extra payment to provide access to edit specific DNS records besides the name servers.
