Having full control of your domains is something very necessary and to be able to access and edit the DNS records for any of them is one of the things you have to look for when you search for a registration or a shared web hosting provider. Maybe you have heard of the so-called “name servers” that show where a domain address is hosted, but below them there's a whole list of records, such as 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. These records are used if you would like have your website with one provider and the e-mails with another, as an illustration. You may also use a domain name for a non-website service or forward the traffic to it by using special records. Some companies ask for an additional fee to grant access to edit specific DNS records besides the name servers.
