Having 100 % control of your domains is something quite necessary and to be able to access and edit the DNS records for every one 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 of the so-called “name servers” that show where a domain is hosted, but below them there is a whole set 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 e-mails for a specific domain name. These records are employed if you wish to have your site with one service provider and the e-mails with another, for instance. You may also use a domain name for a non-website service or direct the traffic to it using special records. A lot of companies ask for an extra fee to provide access to edit particular DNS records apart from the name servers.
