Having full control of your domain names is something very important and being able to access and edit the DNS records for each of them is one of the things you have to look for when you search for a registration or a shared hosting provider. You may have heard of the so-called “name servers” that show where a domain is hosted, but below them there's a whole list of records, for example 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 particular domain. These records are employed if you would like have your website with one service provider and the e-mails with another, for example. Additionally you can use a domain address for a non-website service or forward the traffic to it by using special records. Some companies ask for an extra fee to give access to edit specific DNS records other than the name servers.
