<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/{qname}[/{rtype}[/{value}]]</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>Optional. The resource type: <code>A</code> (an IPv4 address; the default), <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>Optional-ish. The new record’s value. If not provided, the IPv4 address of the remote host is used — this is handy for dynamic DNS! You can also set this in a POST parameter. To delete a record, pass “value=” in the POST body.</td></tr>
|
|
</table>
|
|
|
|
<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
|
|
|
|
# sets a TXT record
|
|
curl -d "value=something%20here" --user me@mydomain.com:###### https://{{hostname}}/admin/dns/set/foo.mydomain.com/txt
|
|
|
|
# clears the TXT record
|
|
curl -d "value=" --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. We do not recommend this.</p>
|
|
|
|
<p>If you do so, you are responsible for keeping your DNS entries up to date. In particular DNSSEC entries must be re-signed periodically. Do not set a DS record at your registrar or publish DNSSEC entries in your DNS zones if you do not intend to keep them up to date.</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>
|
