Having 100 % control over your domain names is something quite important and to be able to access and edit the DNS records for any of them is among the things you need to look for when you search for a registration or a hosting provider. Perhaps you have heard of the so-called “name servers” that show where a domain name is hosted, but below them there's a whole group of records, for example the A record, which is the IP address of the server hosting the website, and the MX records, which show the server that handles the emails for a specific domain name. These records are used if you would like have your web site with one provider and the e-mails with another, as an illustration. You can also use a domain name for a non-website service or direct the traffic to it using special records. Many companies ask for an extra payment to grant access to edit certain DNS records apart from the name servers.
