DOMAIN NAME HOSTING:
Once you’ve registered a domain name, your domain name registrar will probably point it to a webpage that they’ve configured. This page may have ads on it – that way they can make money from your domain name!
If you need it to point to your website, you will need to update the authoritative DNS servers to be those of your website hosting provider. Your web hosting provider can provide you with these details. Once you’ve received them, you should be able to log in to a control panel via your domain name registrar’s website. This control panel should have an option for you to update the authoritative DNS servers of your domain name.
