<h1>Require network addresses</h1>
|
|
|
|
<p>This field is optional.</p>
|
|
|
|
<p>You can restrict access for a quiz to particular subnets
|
|
on the LAN or Internet by specifying a comma-separated list of
|
|
partial or full IP address numbers.</p>
|
|
|
|
<p>This is especially useful for a proctored quiz, where you want
|
|
to be sure that only people in a certain room are able to
|
|
access the quiz.</p>
|
|
|
|
<p>For example: <b>192.168. , 231.54.211.0/20, 231.3.56.211, 231.3.56.10-20</b></p>
|
|
|
|
<p>There are four types of numbers you can use (you can not use
|
|
text based domain names like example.com):</p>
|
|
|
|
<ol>
|
|
<li>Full IP addresses, such as <b>192.168.10.1</b> which will match
|
|
a single computer (or proxy).</li>
|
|
<li>Partial addresses, such as <b>192.168</b> which will match anything
|
|
starting with those numbers.</li>
|
|
<li>CIDR notation, such as <b>231.54.211.0/20</b> which allows you to specify
|
|
more detailed subnets.</li>
|
|
<li>A range of IP addresses <b>231.3.56.10-20</b> The range applies to the last
|
|
part of the address, so this means all the IP addresses from 231.3.56.10
|
|
to 231.3.56.20.</li>
|
|
</ol>
|
|
|
|
<p>Spaces are ignored.</p>
