Having total control over your domain names is something quite necessary and to be able to access and edit the DNS records for every single one of them is one of the things you have to look for when you search for a registration or a web hosting provider. You might have heard of the so-called “name servers” that show where a domain is hosted, but below them there is a whole group 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 certain domain address. These records are employed if you would like have your web site with one provider and the e-mails with another, as an illustration. You could also use a domain for a non-website service or direct the traffic to it using special records. Some companies ask for an additional payment to give access to edit particular DNS records other than the name servers.
