If you're creating a website using Hostinger Website Builder, your domain name must be pointed to Hostinger servers.
If your domain is registered at Hostinger, it's pointed to Hostinger servers by default. However, if you're using a third-party domain (that's not registered at Hostinger), you'd simply need to update your domain's nameservers manually.
