Hello Everyone, I need your help to know about this portal.

So there is a website where I can search for all the active websites using a particular keyword in their domain URL. So for example, if there is a keyword "digital", I want to be entering this keyword in this website and this website shud give me all the active websites which are using Digital keyword in their domain name, I shud be able to get this list with all permutations and combinations. So maybe a website is hellodigital.com or digitalgeek.com etc if these 2 websites r active then i need it on my list. Pls help with the same.
