ISPconfig 3 is a popular open-source tool for managing hosting, servers, and domains. With its flexibility and wide range of features, it's an ideal solution for web administrators looking for an efficient way to manage their web environment. One of its key features is the ability to easily manage subdomains. This article will provide you with a detailed guide on how to do just that.

What are Subdomains and Why Use Them

Subdomains are extensions of the main domain that allow you to organize your website into logically separated sections without the need to register a new domain. For example, blog.yourdomain.com is a subdomain of the domain yourdomain.com. Subdomains are ideal for dividing a website into different sections, such as blogs, e-commerce stores, or forums.

Basics of Managing Subdomains in ISPConfig 3

ISPConfig 3 provides an intuitive interface for managing subdomains. To add a new subdomain, you first need to log in to the ISPConfig 3 control panel and navigate to the "Websites" section.

Adding a New Subdomain

1. Log in to your ISPConfig 3 control panel.
2. Go to the "Websites" section and select "Add new website".
3. In the "Domain" section, enter the name of your subdomain, for example, blog.yourdomain.com.
4. Fill in the other required information and save the settings.

Setting up DNS for Subdomains

For proper functionality of subdomains, it's necessary to configure DNS records correctly. In ISPConfig 3, you can do this directly in the panel under the "DNS" section.

1. Go to the "DNS" section and select "Add new record".
2. Choose the record type, usually A or CNAME, and fill in the necessary information, such as the subdomain name and the server's IP address.
3. Save the changes.

Advanced Tips for Managing Subdomains

• Use SSL certificates to secure subdomains. ISPConfig 3 allows easy installation of Let's Encrypt certificates.
• Utilize subdomain redirections if you want to quickly redirect visitors to another part of your website or to a completely different website.
• For better organization and management, take advantage of the ability to set PHP version and other server parameters for each subdomain separately.

Managing subdomains in ISPConfig 3 is simple and intuitive. With the help of this guide, you can efficiently expand your web environment with subdomains, which will help better organize your content and provide users with improved navigation. Remember to regularly check the settings and security of your subdomains to ensure smooth and secure operation.
