What kind of paint is this and prep required?

[UnusualCapybara]

The house we recently moved into is painted exclusively in this magnolia paint which has an unusual texture. There's a picture below but the easiest way to put it is that it has quite a hard and shiny finish, and areas can be peeled off whole.

Any guidance on what kind of paint this is likely to be, and what prep if any is required to paint over it?

It could well be an exterior smooth paint, the texture looks to be the actual wall not the paint. If it’s peeling like that I’d say the wall are powdery, rub your fingers over the exposed part of the wall, do you get residue on your fingers; like a whiteish dust?
