It is easy to build a website by following the website building knowledge from Naibabiji. However, Naiba has learned that many novice users are still confused about some basic terms, such as the subdomain introduced in this article.
Those who are preparing to build a website should at least know what a domain name is. A domain name is what we call a website address.
To get your own domain name, directly refer to Naiba'sDomain Topic Articlesto register and purchase one.
What is a subdomain?
A subdomain is also called a subdomain name.
Take the domain name of Naibabiji as an example, and you will understand.
The main domain of Naibabiji is naibabiji.com
www.naibabiji.com and blog.naibabiji.com are both subdomains.
That's right, only a domain name without anything else is the main domain. As long as www. or other blog. is added, these are subdomains.
What is the function of a subdomain?
The main purpose of subdomains is to distinguish different website content under the same website.
Some large websites, when they have a lot of content, will consider separating some relatively independent content into a separate website. This is beneficial for content specialization and also for website SEO.
If you apply for a new domain name for each website, it not only wastes resources but also is not conducive to brand building.
So, like the familiar Baidu Zhidao, Baidu Tieba, Baidu Images, Baidu Wenku, etc., they all use subdomains of baidu.com.
How to obtain a subdomain?
As long as you have your own domain name, you can create subdomains under that domain name.
Creating a subdomain is very simple. Just add the corresponding resolution record in the domain name resolution section.
For example, to create the subdomain blog.naibabiji.com, just fill in blog in the resolution record, A record, and fill in the corresponding server IP for the resolution value.
Subdomains can also have multiple levels (Naiba hasn't studied how many levels exactly), but the most seen is two levels of subdomains.
For example, www.blog.naibabiji.com.
