Having full control over your domains is something rather important and being able to access and edit the DNS records for each of them is one of the things you have to look for when you search for a registration or a website 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 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 handles the emails for a certain domain name. These records are employed if you'd like to have your site with one company and the e-mails with another, as an illustration. Additionally you can use a domain for a non-website service or direct the traffic to it by using special records. Some companies ask for an additional payment to provide access to edit certain DNS records besides the name servers.
