 <h3>Rules</h3>
 
+<p class="issue"> Issue 18: What is the behavior for IP addresses? </p>
+
 <p>Rules are the primary component of a selection list. A rule is a line in a selection list that changes the way the user-agent handles third-party content. </p>
 
 <p>Rules are matched against the URI of each third-party subdownload in a page. A URI that has a different second-level domain name than the URI in the address bar is a third-party URI. </p>
