More On IP Address Blocking for Quizzes

I gotten a few questions about the new features, and I wanted to clear up some misconceptions.
Quiz Takers Don’t Need a Question Writer Tracker Account
When you upload a quiz to QWT, you’ll get a link that is available on the public internet – you can give it to anyone, and as long as they have an internet connection, they’ll be able to take the quiz.
You Can Deny Access To a Quiz Based on the User’s IP Address
The new feature allows you to define an IP address that is allowed, or one that is disallowed, or a range of IP addresses that are allowed, or a range of IP addresses that are not allowed, or a combination of these features. There are some simple examples in the orginal post, but here’s a really complicated example to show all the features.
Let’s say your IP Restrict string is
-123.123.78.22; 123.123.*.*; 210.33.*.*;
and a user arrives to take your quiz.
QWT will first check if the user’s IP address is 123.123.78.22. If it is, the user will be denied access (because of the – sign) and no further rules will be evaluated.
If it is not, then QWT will check if the user’s IP address starts with 123.123. – if it does, the user will be allowed access and no further rules will be evaluated.
If it is not, then QWT will check if the user’s IP address starts with 210.33. – if it does, the user will be allowed access.
If it does not, there are no further rules to evaluate, so the user will be denied access.
