Fqdn where to find?

Gerard Tu · Answer

A fully qualified domain name (FQDN) is a part of the uniform resource locator (URL). As the name suggests, it is the full name of an entity in the internet framework, including a host and a computer.

This article will explain the fully qualified domain name’s definition, examples, and functions. Then, we will walk you through how to find an FQDN on the three most commonly used operating systems – Windows, macOS, and Linux.

A fully qualified domain name, also known as an absolute domain name, specifies all domain levels written in the hostname.domain.tld format. For example, a mail server of yahoo.com would be mail.yahoo.com. Other examples include www.wordpress.org and news.bbc.co.uk.

Let’s explore each element on an FQDN hierarchy:

The maximum hostname and fully qualified domain name length is 63 bytes per label and 255 bytes per FQDN.

Like an FQDN, a partially qualified domain name (PQDN) also indicates a web address but only includes a hostname or a domain name.

Generally, website developers configure their sites’ DNS to redirect visitors to the same page whether they type the FQDN or PQDN.

For example, if you type hostinger.com or www.hostinger.com, you will land on https://hostinger.com – the URL for our homepage. PQDNs are usually favorable since they are shorter, helping visitors find the site easier.

FQDNs are usually used in any interaction on the internet as they are easier to remember than IP addresses. Below are several scenarios of when to use an FQDN:

Follow the steps below to find an FQDN on any desktop for Windows users:

Alternatively, use a simple command by right-clicking on the Start Menu and selecting Windows Terminal. Then, enter the ipconfig /all command to reveal a complete Windows IP configuration, including the hostname, primary DNS suffix, and connection-specific DNS Suffix.

For macOS users, click the System Preferences icon in the Dock or navigate to the Apple menu at the left top, select System Preferences, and choose Sharing.

At the top, you should see an FQDN and a connection-specific DNS suffix under the Computer Name section.

Meanwhile, Linux users can find FQDN by entering the hostname –fqdn command line in the Terminal. To open the Terminal, press CTRL + ALT + T or search for it by clicking the Dash icon, typing “terminal” in the search box, and selecting the Terminal application.

A fully qualified domain name (FQDN) enables a specific computer or a server on the internet to be uniquely identified within the domain name system (DNS).

This full domain name contains:

Unlike fully qualified domain names, including complete levels of a domain, partially qualified domain names (PQDNs) consist of only the hostname or domain name – a second-level domain and a domain extension. Since it is shorter, a PQDN helps people remember the address much more quickly.

FQDNs are essential when you want to obtain an SSL certificate, migrate to a different server, or connect to a remote host or a virtual machine. Where to find an FQDN will depend on your operating system. For example, Windows and Linux-based users can check it using the Terminal, while Apple stores FQDNs on the System Preferences panel.
