Unknown URLs are redirecting to homepage (from www.example.com/page/2345343 to www.example.com)

I'm using a WordPress website and I got this issue, I'm not sure it's an issue or feature in WordPress.

When I enter my website name like www.example.com/page/1234234 (random number) or www.example.com/page, it is redirecting to the home page (www.example.com).

And also when I enter pagination in URLs like www.example.com/blog/page2 and it is redirecting to www.example.com/blog/page/2.

Can anyone explain this?
