2. In the "Domains" section, click on the "Zone Editor" Icon.
Under "Domains", you can see many options below the "Actions" text.
3. Click on "A Record" and a small window will pop open. Enter the required details in it.
Name: Enter the name you wish to add, for example, add "blog" and the cPanel will automatically add a domain name like blog.example.com.
Address: Enter the IP Address of the server.
Now click on the "Add an A Record" button.
If the record is added successfully, you will see a success message. The DNS propagation can take up to 24 hours.
