The domain host automatically sets the DNS nameservers to a parked domain. How can the settings be changed so that entering the URL instead gives a null (404) result or blank page?
You cannot do this with "DNS" alone, you will require DNS hosting along with website hosting.
Once you have both DNS, and WEBSITE hosting (the former often provided free of charge by 'most' domain providers); you'll need to do the following:
- Update nameservers (if not done already)
- Update/Create DNS record for your primary zone(domain) with an A record pointing to your hosting provider.
- Depending on your hosting provider, you may simply be able to delete your
index.html(or equivalent) and that'll result in a 404 being shown.
Ultimately most 'consumer'-grade hosting providers will be able to offer you support to do what I have described, with instructions suited to their exact platform.
