No. Don't pass null to is valid, just like you wouldn't pass an array, a DOM node, and so on. |

I believe this function is meant to test values. So why assuming that only strings can be passed to it? On the opposite side we could say pass only valid IPs and therefore this function would be useless. |

Because the fact that a string is passed is a part of its precondition. |
