Having 100 % control of your domains is something quite important and to be able to access and edit the DNS records for any of them is one of the things you need to look for when you search for a registration or a website hosting provider. Perhaps you have heard about 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 site, and the MX records, which show the server that deals with the e-mails for a specific domain name. These records are employed if you wish to have your website with one company and the e-mails with another, for example. Additionally you can use a domain address for a non-website service or forward the traffic to it using special records. Many companies ask for an extra fee to grant access to edit specific DNS records apart from the name servers.
