Having total control over your domain names is something quite crucial and to be able to access and edit the DNS records for every one of them is one of the things you should look for when you search for a registration or a shared hosting provider. You may have heard about the so-called “name servers” that show where a domain is hosted, but below them you will find a whole list 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 certain domain name. These records are employed if you wish to have your web site with one provider and the e-mails with another, for instance. You could also use a domain address for a non-website service or forward the traffic to it by using special records. Some companies ask for an additional payment to give access to edit particular DNS records besides the name servers.
