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 among the things you need to look for when you search for a registration or a shared hosting provider. Perhaps you have heard of the so-called “name servers” that show where a domain is hosted, but below them there's a whole set of records, such as 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 certain domain name. These records are employed if you want to have your site with one provider and the emails with another, as an illustration. You may also use a domain address for a non-website service or direct the traffic to it by using special records. A lot of companies ask for an extra fee to give access to edit certain DNS records besides the name servers.
