Is WWW A Subdomain

What Is A Subdomain?

Before we dive into our article, let’s have a brief recap for those that need it. A subdomain is a piece of information added to the start of your website’s domain name.

The purpose of a subdomain is to allow websites to organize and separate content for a specific function, such as an online store or blog, from the rest of your website.

Domain names typically have two parts:

  • The top-level domain (TLD)
  • The second level domain (SLD)

Your top-level domain is the extension part of your domain, like .com or .org, and can be found at the end of your domain name.

Your second-level domain is part of your domain name that is unique to your website. This might be your brand name, business name, or something unique you have created.

Take our domain name, for example, “yoursimplehosting” is our SLD, and .com is our TLD. How does this relate to the subdomain?

Well, your subdomain goes before the SLD. it sits after your HTTP or HTTPS and acts as a file path for different content on your website.

You might see, the subdomain here indicates that you are reading a blog post, and the rest of the domain name tells you what site you are on!

A few different subdomains are commonly used, but we have more on that coming up in a little bit.
