Having 100 % control over your domain names is something quite crucial 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 shared web hosting provider. You may have heard about the so-called “name servers” that show where a domain name is hosted, but below them you will find a whole set of records, like the A record, which is the IP address of the server hosting the site, and the MX records, which show the server that handles the e-mails for a specific domain name. These records are employed if you'd like to have your website with one company and the e-mails with another, as an illustration. You may also use a domain name for a non-website service or direct the traffic to it using special records. Many companies ask for an extra fee to grant access to edit particular DNS records other than the name servers.
