<h2>DNS (Advanced)</h2>
|
|
|
|
<p class="text-danger">Custom and external DNS are for advanced configurations.</p>
|
|
|
|
<h3>Custom DNS</h3>
|
|
|
|
<p>It is possible to set custom DNS records on domains hosted here. For instance, you can create your own dynamic DNS service. To do so, you will need to call your box’s DNS API.</p>
|
|
|
|
<h4>The HTTP POST request</h4>
|
|
|
|
<p>Send a POST request like this:</p>
|
|
|
|
<pre>curl -d "" --user {email}:{password} https://{{hostname}}/admin/dns/set/<b>qname</b>[/<b>rtype</b>[/<b>value</b>]]</pre>
|
|
|
|
<table class="table">
|
|
<thead><th>Parameter</th> <th>Value</th></thead>
|
|
<tr><td>email</td> <td>The email address of any administrative user here.</td></tr>
|
|
<tr><td>password</td> <td>That user’s password.</td></tr>
|
|
<tr><td>qname</td> <td>The fully qualified domain name for the record you are trying to set.</td></tr>
|
|
<tr><td>rtype</td> <td>The resource type. <code>A</code> if omitted. Possible values: <code>A</code> (an IPv4 address), <code>AAAA</code> (an IPv6 address), <code>TXT</code> (a text string), or <code>CNAME</code> (an alias, which is a fully qualified domain name).</td></tr>
|
|
<tr><td>value</td> <td>The new record’s value. If omitted, the IPv4 address of the remote host is used. This is handy for dynamic DNS! To delete a record, use “__delete__”.</td></tr>
|
|
</table>
|
|
|
|
<p style="margin-top: 1em">Note that <code>-d ""</code> is merely to ensure curl sends a POST request. You do not need to put anything inside the quotes. You can also pass the value using typical form encoding in the POST body.</p>
|
|
|
|
<h4>Examples:</h4>
|
|
|
|
<pre># sets laptop.mydomain.com to point to the IP address of the machine you are executing curl on
|
|
curl -d "" --user me@mydomain.com:###### https://{{hostname}}/admin/dns/set/laptop.mydomain.com
|
|
|
|
# sets an alias
|
|
curl -d "" --user me@mydomain.com:###### https://{{hostname}}/admin/dns/set/foo.mydomain.com/cname/bar.mydomain.com
|
|
|
|
# clears the alias
|
|
curl -d "" --user me@mydomain.com:###### https://{{hostname}}/admin/dns/set/bar.mydomain.com/cname/__delete__
|
|
|
|
# sets a TXT record using the alternate value syntax
|
|
curl -d "value=something%20here" --user me@mydomain.com:###### https://{{hostname}}/admin/dns/set/foo.mydomain.com/txt
|
|
</pre>
|
|
|
|
|
|
<h3>External DNS</h3>
|
|
|
|
<p>Although your box is configured to serve its own DNS, it is possible to host your DNS elsewhere.</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>
|
|
|
|
<p>Enter the following DNS entries at your DNS provider:</p>
|
|
|
|
<table id="external_dns_settings" class="table">
|
|
<thead>
|
|
<tr>
|
|
<th>QName</th>
|
|
<th>Type</th>
|
|
<th>Value</th>
|
|
</tr>
|
|
</thead>
|

|
