Point to a specific page if url can't be found on digital ocean (vanity) name server

[DaanVbn]

Hi all, I’m using ns1.myvanityserver.com etc that point to the name servers form digital ocean.

Would there be any way if a domain can’t be resolved, the name server points to a specific url?

Background:

I use WHMCS with VPS servers on plesk, when an domain is registered with hosting, everything is fine. The domain and hosting package are created on the plesk servers > plesk server updates ns*.myvanityserver.com. Domain is registered with name servers > ns*.myvanityserver.com. It works great.

The problem arises when a domain is registered without hosting.The domain is still registerd with ns*.myvanityserver.com, but there’s nothing there… Now I would like to point to a ‘this page is hosted at’ page.

Does anyone have a solution for this? Thanks
