I thought QHostAddress was it, but it strangely does not provide methods for validating whether or not the IP address is valid (anymore, got deprecated to Qt3).

Does anyone know?

    Here is the official answer from Nokia support engineer, name removed for privacy protection:

    I posted a question on stackoverflow.com as follow:

    Does Qt provide a class that represents an IP address?

    You can see that someone posted a solution to my question already.

    However, I want to ask how come Nokia doesn’t just provide a method to

    QHostAddress ( like isValid() ) that will check the host address’s
    validity?

    Thank you for your inquiry. You can
    use the isNull() method to check the
    validity. It will return true for
    invalid addresses:
    http://doc.qt.digia.com/4.6/qhostaddress.html#isNull

    Hope this helps.

    Support Engineer, Qt Development
