Having full control over your domains is something really important and to be able to access and edit the DNS records for any of them is one of the things you should look for when you search for a registration or a hosting provider. Maybe you have heard about the so-called “name servers” that show where a domain address is hosted, but below them there is also a whole group 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 deals with the e-mails for a certain domain name. These records are used if you would like have your website with one provider and the e-mails with another, for instance. You may also use a domain address for a non-website service or forward the traffic to it using special records. Some companies ask for an extra payment to grant access to edit particular DNS records besides the name servers.
