<p>You can set additional DNS records, such as if you have a website running on another server, to add DKIM records for external mail providers, or for various confirmation-of-ownership tests.</p>
<optionvalue="CAA"data-hint="Enter a CA that can issue certificates for this domain in the form of FLAG TAG VALUE. (0 issuewild "letsencrypt.org")">CAA (Certificate Authority Authorization)</option>
<optionvalue="MX"data-hint="Enter record in the form of PRIORITY DOMAIN., including trailing period (e.g. 20 mx.example.com.).">MX (mail exchanger)</option>
<optionvalue="SRV"data-hint="Enter record in the form of PRIORITY WEIGHT PORT TARGET., including trailing period (e.g. 10 10 5060 sip.example.com.).">SRV (service record)</option>
<p>If your TLD requires you to have two separate nameservers, you can either set up <ahref="#"onclick="return show_panel('external_dns')">external DNS</a> and ignore the DNS server on this box entirely, or use the DNS server on this box but add a secondary (aka “slave”) nameserver.</p>
<p>If you choose to use a secondary nameserver, you must find a secondary nameserver service provider. Your domain name registrar or virtual cloud provider may provide this service for you. Once you set up the secondary nameserver service, enter the hostname (not the IP address) of <em>their</em> secondary nameserver in the box below.</p>
<tr><td>GET</td><td>Returns matching custom DNS records as a JSON array of objects. Each object has the keys <code>qname</code>, <code>rtype</code>, and <code>value</code>. The optional <code>qname</code> and <code>rtype</code> parameters in the request URL filter the records returned in the response. The request body (<code>-d "..."</code>) must be omitted.</td></tr>
<tr><td>PUT</td><td>Sets a custom DNS record replacing any existing records with the same <code>qname</code> and <code>rtype</code>. Use PUT (instead of POST) when you only have one value for a <code>qname</code> and <code>rtype</code>, such as typical <code>A</code> records (without round-robin).</td></tr>
<tr><td>POST</td><td>Adds a new custom DNS record. Use POST when you have multiple <code>TXT</code> records or round-robin <code>A</code> records. (PUT would delete previously added records.)</td></tr>
<tr><td>DELETE</td><td>Deletes custom DNS records. If the request body (<code>-d "..."</code>) is empty or omitted, deletes all records matching the <code>qname</code> and <code>rtype</code>. If the request body is present, deletes only the record matching the <code>qname</code>, <code>rtype</code> and value.</td></tr>
<tr><td>qname</td><td>The fully qualified domain name for the record you are trying to set. It must be one of the domain names or a subdomain of one of the domain names hosted on this box. (Add mail users or aliases to add new domains.)</td></tr>
<tr><td>rtype</td><td>The resource type. Defaults to <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), <code>CNAME</code> (an alias, which is a fully qualified domain name — don’t forget the final period), <code>MX</code>, <code>SRV</code>, <code>SSHFP</code>, <code>CAA</code> or <code>NS</code>.</td></tr>
<tr><td>value</td><td>For PUT, POST, and DELETE, the record’s value. If the <code>rtype</code> is <code>A</code> or <code>AAAA</code> and <code>value</code> is empty or omitted, the IPv4 or IPv6 address of the remote host is used (be sure to use the <code>-4</code> or <code>-6</code> options to curl). This is handy for dynamic DNS!</td></tr>
<p>Strict <ahref="http://tools.ietf.org/html/rfc4408">SPF</a> and <ahref="https://datatracker.ietf.org/doc/draft-kucherawy-dmarc-base/?include_text=1">DMARC</a> records will be added to all custom domains unless you override them.</p>
<p>Try these examples. For simplicity the examples omit the <code>--user me@mydomain.com:yourpassword</code> command line argument which you must fill in with your email address and password.</p>
