If you enter anything into the Require password field, the student must enter that password to access the quiz.
With Require network address, you can restrict access to the quiz to particular IP address/addresses. For example, you can restrict the quiz's access to the following IP addresses:
- 146.203.59.235: This is a single IP address. It will permit a single computer to access the quiz. If this computer is acting as a proxy server, the other computers behind it can also access the quiz.
- 146.203: This is a range of IP addresses. It will permit any IP address starting with those numbers. If those numbers belong to your company, you effectively limit access to the quiz to your company's campus.
- 146.203.59.235/20 ...
