Having total control of your domain names is something rather important and to be able to access and edit the DNS records for any of them is among the things you should 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 list of records, like the A record, which is the IP address of the server hosting the website, and the MX records, which show the server that deals with the e-mails for a specific domain address. These records are employed if you would like have your web site with one service provider and the emails with another, for example. You may 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 extra payment to give access to edit particular DNS records besides the name servers.
