When you park a domain name on Hostinger's DNS system, it means you've associated that domain with your Hostinger hosting account. This allows visitors to access your website using that domain. Typically, the parked domain will display the same content as your main domain, and it's a way to have multiple domain names pointing to the same website. This is useful if you have variations of your domain or if you want to capture traffic from multiple domain names. The process usually involves updating the domain's DNS settings to point to Hostinger's servers, and you may need to configure the parked domain within your hosting account. Keep in mind that specific steps might vary based on Hostinger's interface and updates to their system.
