Basics of Building Your Own Website: What is a Subdomain

Building a website yourself by following the website building knowledge from Naibabiji is easy. However, during the process, Naiba has learned that many novice users are still confused about some basic terms, such as the subdomain introduced in this article. Friends preparing to build a website should at least know what a domain name is; a domain name is what we call a website address.

What is a subdomain?

A subdomain is also called a subdomain name. Using Naibabiji's domain name as an example will make it clear. The primary domain name of Naibabiji is naibabiji.com. Both www.naibabiji.com and blog.naibabiji.com are subdomains. That's right, only the domain name with nothing added is the primary domain name; anything with www. or other prefixes like blog. is a subdomain.

What is the purpose of a subdomain?

The main purpose of a subdomain is to distinguish different website content under the same website. After large websites accumulate a lot of content, they often consider separating relatively independent content into a standalone website. This is beneficial for content focus and also for website SEO. Applying for a new domain name for each website would not only waste resources but also be detrimental to brand building. Therefore, familiar examples like Baidu Zhidao, Baidu Tieba, Baidu Images, and Baidu Wenku all use subdomains of baidu.com.

How to obtain a subdomain?

As long as you own your own domain name, you can create subdomains under that domain. Creating a subdomain is simple; you just need to add the corresponding DNS record in the domain resolution settings. For example, to add the blog.naibabiji.com subdomain, you only need to fill in 'blog' for the record, select A record, and fill in the corresponding server IP for the resolution value. Subdomains can also be multi-level (the specific maximum number of levels Naiba hasn't researched), with the most seen being two-level subdomains. For example, www.blog.naibabiji.com.
