|
||
|
|
<div><p>Domain Name System (DNS) servers running BIND 8 can be configured
|
||
|
|
to accept requests from other sources to update zone data dynamically. This
|
||
|
|
topic provides instructions for configuring the allow-update option so DNS
|
||
|
|
can receive dynamic updates.</p>
|
||
|
|
<div class="section"><p>When creating dynamic zones, you should consider your network
|
||
|
|
structure. If parts of your domain still requires manual updates, you might
|
||
|
|
want to consider setting up separate static and dynamic zones. If you have
|
||
|
|
to make manual updates to a dynamic zone, you must stop the dynamic zone server
|
||
|
|
and restart it after you have completed the updates. Stopping the server forces
|
||
|
|
it to synchronize all dynamic updates that have been made since the server
|
||
|
|
loaded its zone data from the zone database. If you do not stop the server,
|
||
|
|
you will lose all dynamic updates that are processed since it is started.
|
||
|
|
However, stopping the server to make manual updates means you might miss dynamic
|
||
|
|
updates that are sent while the server is down.</p>
|
||
|
|
<p>DNS indicates that a
|
||
|
|
zone is dynamic when objects are defined in the allow-update statement. To
|
||
|
|
configure the allow-update option, follow these steps:</p>
