How to redirect all http trafic to one site

I need all requests in browser redirect to duckduckgo.com. How to do it?

What do you want to achieve?

But are you talking about MikroTik products or how to configure the browser’s default search engine?

It can’t be done, duckduckgo also works in https and redirecting it does nothing but give only errors.

Apparently there is no way to control a PC that has DNS set to something other than what the admin wants the user to use ???
