For IPv6, this is the IP address of an automatically configured interface

|

that is beyond your local server but attached to the LAN.</p>
|

<p>To ping your

own server to troubleshoot the problem, follow these steps:</p>

</div>
|

<ol><li class="stepexpand"><span>At the command line, type these commands:</span><ul><li>For IPv4: <samp class="codeph">PING 'nnn.nnn.nnn.nnn'</samp> or <samp class="codeph">PING <em>hostname</em></samp></li>

Ping parameters can be used to tune the Ping command to get the most

accurate results. Prompt on the Ping command by selecting F4 for complete

details on the Ping parameters.</li>
