Having total control over your domains is something quite important and being able to access and edit the DNS records for every single one of them is among the things you have to look for when you search for a registration or a shared website hosting provider. Perhaps you have heard about the so-called “name servers” that show where a domain is hosted, but below them there is also a whole list 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 handles the e-mails for a particular domain address. These records are used if you'd like to have your website with one company and the emails with another, for example. You may also use a domain for a non-website service or forward the traffic to it by using special records. Some companies ask for an additional payment to provide access to edit particular DNS records apart from the name servers.
