Internet experience is a part of our daily lives, and domain names are an integral part of any Internet presence and experience. The domain name system (DNS) is a critical component of the internet infrastructure that ensures the verification, locations, and authentication of websites.
It is sort of an online equivalent of an address. The DNS allows the laymen to read the loosely translated complex IP addresses.
Web and domain hosting are practically incomplete when it comes to domain names. Fully qualified domain names and partially qualified domain names are two sectors of this system.
These are two important concepts regarding web and domain hosting. These aspects help us navigate the internet with ease and make it user-friendly. All of these factors make it paramount.
If you are someone who hosts a website on the internet, you should understand these concepts to have a more comprehensive and nuanced understanding of the internet experience.
This blog will talk about fully qualified domain names with the help of a few examples.
Fully Qualified Domain Name
When a device or server is connected to the internet or a private network, they are assigned an identity to make them easily identifiable. These unique identifiers are called fully qualified domain names (FQDN).
The fully qualified domain names include top-level domains and second-level domains as well. These domain names are visible with some components like dots that separate a series of labels that represent the hierarchy in that domain.
This keeps internet addresses readable for humans instead of them having to remember complicated IP addresses. You will only have to enter the qualified domain name, and you will be redirected to the website.
Before moving on to the examples of fully qualified domain names, let us understand the partially qualified domain names.
Partially Qualified Domain Name
The partially qualified domain names do not include top-level domains; they only include second-level domains.
For example, a partially qualified domain name will look something like this: “mail.domain.com”!
These are a little inadequate for website hosting as compared to the fully qualified domains.
That’s why it is always advised for you to issue fully qualified domains instead of their partially qualified counterparts.
Fully Qualified Domain Names (FQDN) Examples
This is a typical fully qualified domain name example. Here the labels are as follows: (www) is the hostname, (websitename) is a second-level domain name, and (com) is a top-level domain name.
- mailserver.websitename.com
This is another example of a fully qualified domain name. The (mailserver) is the hostname, (websitename) is again the second-level domain name, and (com) is a top-level domain name.
- ftp-downloads.domainwebsitename.com
This is also an FQDN where the (ftp-downloads) is a hostname, (domainwebsitename) is a second-level domain name, and again (com) is the top-level domain name.
Ending Note
Understanding the examples and importance of a fully qualified domain name is essential for every website owner. This leads to a comprehensive as well as unique perspective towards the internet experience.
That is because of how detailed and minute these aspects are. The unique identification system called the domain name system is completely resourceful for locating these websites.
These components of the internet infrastructure keep us connected, and hence, learning about them is very important!
