A fully qualified domain name, or FQDN, is the complete name of a specific place on the internet. It tells computers exactly which website or service you want to reach.
For example, www.datapacket.net is an FQDN. The datapacket.net part is the domain name, and www identifies the website. A name such as mail.datapacket.net could identify a mail server.
You may also see an FQDN written with a dot at the end, like www.datapacket.net.. That final dot marks the end of the name in the Domain Name System (DNS). Most people never need to type it.
When you enter an FQDN in a browser, DNS finds the server connected to that name. Think of it like looking up an address so your browser knows where to go.
To use your own domain name, you first need to register one that is available. You can search for and register a domain through DataPacket. Once you have a domain, you can set up names for your website, email, and other services.
