<p>The XMPP ping protocol is extremely simple:</p>
<ol>
<li>The pinging entity sends an IQ-get containing a &lt;ping/&gt; element qualified by the 'http://www.xmpp.org/extensions/xep-0199.html#ns' namespace &NSNOTE;.</li>
<li>The pinged entity returns either an IQ-result (if it supports the namespace) or an IQ-error (if it does not). <note>The pinged entity MAY ignore the IQ (i.e., return neither a result nor an error) if doing so would reveal its presence information to an entity that is not authorized to view that information; this mainly applies to client-to-client pings.</note></li>
<li>The pinged entity returns either an IQ-result (if it supports the namespace) or an IQ-error (if it does not). (See the <link url='#security'>Security Considerations</link> regarding leaks of presence information in the context of pings sent to clients.)</li>

<p>A pinged entity MAY ignore the IQ (i.e., return neither a result nor an error) if doing so would reveal its presence (network availability) information to an entity that is not authorized to view that information; this mainly applies to pings sent to clients (where the response would reveal client availability) but may apply to other entities as well.</p>
