Having total control over your domains is something rather important and to be able to access and edit the DNS records for every single one of them is one of 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 also a whole set of records, like the A record, which is the IP address of the server hosting the site, and the MX records, which show the server that manages the e-mails for a particular domain address. These records are used if you would like have your website with one provider and the e-mails with another, for instance. You could also use a domain address for a non-website service or direct the traffic to it through special records. A lot of companies ask for an additional payment to grant access to edit specific DNS records apart from the name servers.
