   1 <h1>Require network addresses</h1>
   2
   3 <p>This field is optional.</p>
   4
   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>
  12
  13 <p>For example: <b>192.168. , 231.54.211.0/20, 231.3.56.211, 231.3.56.10-20</b></p>
  14
  15 <p>There are four types of numbers you can use (you can not use
  16    text based domain names like example.com):</p>
  17
  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>
  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>
  28 </ol>
  29
  30 <p>Spaces are ignored.</p>
