<h2>External DNS</h2>
|
|
|
|
<p class="text-warning">This is an advanced configuration page.</p>
|
|
|
|
<p>Although your box is configured to serve its own DNS, it is possible to host your DNS elsewhere — such as in the DNS control panel provided by your domain name registrar or virtual cloud provider — by copying the DNS zone information shown in the table below into your external DNS server’s control panel.</p>
|
|
|
|
<p>If you do so, you are responsible for keeping your DNS entries up to date! If you previously enabled DNSSEC on your domain name by setting a DS record at your registrar, you will likely have to turn it off before changing nameservers.</p>

You may encounter zone file errors when attempting to create a TXT record with a long string.
|
|
<a href="http://tools.ietf.org/html/rfc4408#section-3.1.3">RFC 4408</a> states a TXT record is allowed to contain multiple strings, and this technique can be used to construct records that would exceed the 255-byte maximum length.
|
|
You may need to adopt this technique when adding DomainKeys. Use a tool like <code>named-checkzone</code> to validate your zone file.
