ISPconfig 3 is a popular open-source tool for web hosting management, allowing the administration of web servers, emails, databases, and DNS via a web interface. One of ISPConfig 3's key features is the management of DNS records, essential for the proper functioning of your domains and services. This article will guide you through the basic configuration of DNS records in ISPConfig 3, enabling you to efficiently manage your domains.

DNS Basics

DNS (Domain Name System) is a system that translates human-readable domain names (e.g., www.example.com) into IP addresses (e.g., 192.0.2.1) that computers use to establish connections. Every domain must have properly configured DNS records to be accessible on the internet.

Logging into ISPConfig 3

Before you begin configuring DNS records, you need to log in to your ISPConfig 3 panel. Enter the URL of your panel into a web browser and log in using your credentials.

Creating a New DNS Zone

1. After logging in, click on the "DNS" tab.
2. Select "DNS Zones" and click on the "Add new zone" button.
3. Fill in the necessary information about your domain, such as the zone name and the IP address of the primary server. Once completed, click "Save."

Configuring DNS Records

For the basic functionality of your domain, you'll need to set up several types of DNS records:

• An A record is used to map a domain name to a server's IP address.
• An MX record specifies the mail server responsible for receiving emails for your domain.
• A CNAME record allows you to assign an alias to an existing domain name.
• A TXT record is often used for domain verification or setting SPF rules.

1. In the DNS zone, click on "Add record."
2. Choose the type of record you wish to add and fill in the required information.
3. Once done, click "Save."

Testing DNS Configuration

After configuring DNS records, it's essential to verify that they are properly propagated, and your domain is correctly recognized on the internet. You can use tools like nslookup or dig to check if your records are functioning as intended.

Proper DNS record configuration is crucial for the availability of your domain and services on the internet. With ISPConfig 3, you can easily manage your DNS records and ensure the proper functionality of your websites and emails. Remember to regularly check and update your DNS records to match the current needs of your infrastructure.
