Configuring hosted DNS servers<br />

10-16 Domain Name System (DNS)<br />

3. To enable the allow-query option, select the corresponding check box.<br />

Enabling this option allows you to limit who is able to query this name<br />

server. If enabled, only the requesters defined in the allow-query list will<br />

be authorized to query this name server. Use the New and Delete<br />

buttons to modify this list. See “Adding an IP address” on page 10-16 for<br />

details on using the New button.<br />

By default the allow-query option is not enabled, meaning all requesters<br />

are authorized to query the name server.<br />

4. To enable the allow-transfer option, select the corresponding check<br />

box. Enabling this option allows you to limit who is authorized to<br />

request zone file transfers from this name server. If enabled, the name<br />

server will only transfer zone files to requesters defined in the allowtransfer<br />

list. Use the New and Delete buttons to modify this list. See<br />

“Adding an IP address” on page 10-16 for details.<br />

By default the allow-transfer option is not enabled, meaning the name<br />

server will transfer zone files to all requesters.<br />

5. Click OK to save your changes.<br />

Adding an IP address This window is used to add a new IP address to the selected list in the<br />

Advanced Server Options window. To add a new IP address, type the<br />

IP address <strong>of</strong> the name server you want to add in the IP Address field.<br />

Click Add and then click Close to add the specified IP address to the<br />

name server list.<br />

Configuring the Zones tab<br />

A DNS server is responsible for serving one or more zones. A zone is<br />

a distinct portion <strong>of</strong> the domain name space. A zone consists <strong>of</strong> a<br />

domain or a subdomain (for example, securecomputing.com or<br />

sales.securecomputing.com). Each DNS server can be configured as<br />

either a master name server or a slave name server for a zone.<br />

When you select the Zones tab, a window similar to the following<br />

appears.
