Can mock server be accessible from outside?

I want to mock my APIs and access those APIs from another computer.
But the mock server URL is in https://06ac3f1d-13f1-4bf7-b5fd-713dcb5bb0d8.mock.pstmn.io/PATH
form. I cannot figure out how to access it by http://ip:port/PATH form.
Is it possible to do that in Postman?
