Having complete control of your domains is something very important and being able to access and edit the DNS records for every one of them is among the things you need to look for when you search for a registration or a cloud web hosting provider. Maybe you have heard about the so-called “name servers” that show where a domain address is hosted, but below them there's a whole group 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 e-mails for a specific domain address. These records are used if you want to have your website with one service provider and the e-mails with another, as an illustration. You may also use a domain for a non-website service or direct the traffic to it through special records. Some companies ask for an extra fee to give access to edit certain DNS records apart from the name servers.
