+      <para>
+        To reload both the configuration file and zones, type the following at a shell prompt:
+      </para>
+      <screen>~]# <command>rndc reload</command>
+server reload successful</screen>
+      <para>
+        This will reload the zones while keeping all previously cached responses, so that you can make changes to the zone files without losing all stored name resolutions.
+      </para>
+      <para>
+        To reload a single zone, specify its name after the <command>reload</command> command, for example:
+      </para>
+      <screen>~]# <command>rndc reload localhost</command>
+zone reload up-to-date</screen>
+      <para>
+        Finally, to reload the configuration file and newly added zones only, type:
+      </para>
+      <screen>~]# <command>rndc reconfig</command></screen>
+      <note>
+        <title>Note: Modyfying Zones with Dynamic DNS</title>
+        <para>
+          If you intend to manually modify a zone that uses Dynamic DNS (DDNS), make sure you run the <command>freeze</command> command first:
+        </para>
+        <screen>~]# <command>rndc freeze localhost</command></screen>
+        <para>
+          Once you are finished, run the <command>thaw</command> command to allow the DDNS again and reload the zone:
+        </para>
+        <screen>~]# <command>rndc thaw localhost</command>
+The zone reload and thaw was successful.</screen>
