<h1>DNS Cache Table</h1>

<p>The DNS cache table allows you to create an alias for an external host 
 and to access that host from the NetScreen device. It also allows you 
 to view current table entries as they occur.</p>

<p><span style="font-weight: bold;">Note:</span> The DNS cache table is 
 local to the device, and functions only as a proxy for the actual DNS 
 server. Consequently, other network nodes cannot query the listed names 
 using the device.</p>

<p>Use the <span style="font-weight: bold;">List ... Cache Table</span> 
 drop-down to specify the table entry type. You can specify any of the following 
 entry types:</p>

<ul style="list-style: disc;"
	type=disc>
	
	<li class=kadov-p><p><span style="font-weight: bold;">Static</span> 
 entries are entries that you define. The device does not generate these 
 entries spontaneously.</p></li>
	
	<li class=kadov-p><p><span style="font-weight: bold;">Dynamic</span> 
 entries are generated by the device spontaneously, representing DNS inquiries 
 made by the device itself.</p></li>
	
	<li class=kadov-p><p><span style="font-weight: bold;">Unresolved</span> 
 entries represent unsuccessful attempts by the device to resolve DNS queries 
 sent to the DNS server.</p></li>
</ul>

<p>The elements of the DNS cache table are as follows:</p>

<ul style="list-style: disc;"
	type=disc>
	
	<li class=kadov-P><p><span style="font-weight: bold;">Host Name:</span> 
 Specifies a host name with which to represents a host device.</p></li>
	
	<li class=kadov-P><p><span style="font-weight: bold;">IP:</span> Specifies 
 the IP address of the host device. For an unresolved entry, <span style="font-weight: bold;">Last 
 IP</span> Specifies the IP address of the last host device that sent an 
 unsuccessful DNS request.</p></li>
</ul>

<p>Each table entry allows you to reach the specified host from the device 
 using the <span style="font-weight: bold;">Host Name</span> value. For 
 example, a DNS table entry might contain an entry named &quot;acme&quot; 
 with an IP address of 2.2.2.25. This entry allows you to reach the host 
 from the device by using the <span style="font-weight: bold;">Host Name</span> 
 value as the identifier. (For example, you could reach the device with 
 the CLI command <span style="font-weight: bold;">ping acme</span>.)</p>
