Having total control over your domain names is something very crucial and to be 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 may have heard about the so-called “name servers” that show where a domain name is hosted, but below them there is also a whole set of records, such as the A record, which is the IP address of the server hosting the website, and the MX records, which show the server that handles the e-mails for a particular domain name. These records are used if you would like have your site with one service provider and the emails with another, for instance. You could also use a domain for a non-website service or direct the traffic to it by using special records. Some companies ask for an extra fee to grant access to edit specific DNS records besides the name servers.
