Having complete control over your domain names is something quite necessary and being able to access and edit the DNS records for every single one of them is among the things you need to look for when you search for a registration or a shared hosting provider. You might have heard about the so-called “name servers” that show where a domain address is hosted, but below them there is 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 manages the emails for a specific domain. These records are used if you want to have your website with one service provider and the emails with another, for instance. Additionally you can use a domain for a non-website service or direct the traffic to it using special records. A lot of companies ask for an additional fee to give access to edit certain DNS records besides the name servers.
