2nd level domain

Hi
is there a plugin to manage 2nd level domain for the same website?

p.e.:

In my website https://www.mywebsite.com I have 3 categories.

Would love to get redirected to:
mountain.mywebsite.com when I’m reading an article in category Mountain
water.mywebsite.com when I’m reading an article in water category.

I can setup up to 30 2nd level domain if necessary.

many thanks
