    I think that it is fine letting the method with default modifier. 
    The point of a test case is that we can/should write tests for a single method. Therefore,
if we want to test the method “getCidrSizeFromString”, we should write a test case for
that specific method, and not for another one that uses it. 
    
    After we make sure that a method works fine, when we test another method (let’s say
“cidrToLong”)  that uses the first one already tested, we can use EasyMock/Mockito or
another test suite to mock the method that we know works, this way we facilitate the writing
of test cases.
