5<p>You can restrict access for a quiz to particular subnets
6 on the LAN or Internet by specifying a comma-separated list of
7 partial or full IP address numbers.</p>
8
9<p>This is especially useful for a proctored quiz, where you want
10 to be sure that only people in a certain room are able to
11 access the quiz.</p>

df907961 13<p>For example: <b>192.168. , 231.54.211.0/20, 231.3.56.211, 231.3.56.10-20</b></p>

df907961 15<p>There are four types of numbers you can use (you can not use
16 text based domain names like example.com):</p>

49aafb90 18<ol>
19<li>Full IP addresses, such as <b>192.168.10.1</b> which will match
20 a single computer (or proxy).</li>
21<li>Partial addresses, such as <b>192.168</b> which will match anything
22 starting with those numbers.</li>
23<li>CIDR notation, such as <b>231.54.211.0/20</b> which allows you to specify
24 more detailed subnets.</li>
df907961 25<li>A range of IP addresses <b>231.3.56.10-20</b> The range applies to the last
26 part of the address, so this means all the IP addresses from 231.3.56.10
27 to 231.3.56.20.</li>
