Can you set your own DNS servers on your client devices? Does cloudflare or quad9 resolve it?
In the Netherlands there’s “Jan Modaal”, modaal (modal) referring the most commonly occurring value in or peak of a distribution. This name is used often when representing the experience of the most average Dutchman.
It’s especially often used in financial discussions and journalism, like “owning a house is getting further out of reach for Jan Modaal.”
