<h2>Overview<aclass="headerlink"href="#overview"title="Permalink to this headline"></a></h2>
<p>mDNS is a multicast UDP service that is used to provide local network service and host discovery.</p>
<p>mDNS is installed by default on most operating systems or is available as separate package. On <codeclass="docutils literal notranslate"><spanclass="pre">Mac</span><spanclass="pre">OS</span></code> it is installed by default and is called <codeclass="docutils literal notranslate"><spanclass="pre">Bonjour</span></code>. Apple releases an installer for <codeclass="docutils literal notranslate"><spanclass="pre">Windows</span></code> that can be found <aclass="reference external"href="https://support.apple.com/downloads/bonjour%2520for%2520windows">on Apple’s support page</a>. On <codeclass="docutils literal notranslate"><spanclass="pre">Linux</span></code>, mDNS is provided by <aclass="reference external"href="https://github.com/lathiat/avahi">avahi</a> and is usually installed by default.</p>

<h3>mDNS Properties<aclass="headerlink"href="#mdns-properties"title="Permalink to this headline"></a></h3>
<blockquote>
<div><ulclass="simple">
<li><p><codeclass="docutils literal notranslate"><spanclass="pre">hostname</span></code>: the hostname that the device will respond to. If not set, the <codeclass="docutils literal notranslate"><spanclass="pre">hostname</span></code> will be read from the interface. Example: <codeclass="docutils literal notranslate"><spanclass="pre">my-esp32</span></code> will resolve to <codeclass="docutils literal notranslate"><spanclass="pre">my-esp32.local</span></code></p></li>
<li><p><codeclass="docutils literal notranslate"><spanclass="pre">default_instance</span></code>: friendly name for your device, like <codeclass="docutils literal notranslate"><spanclass="pre">Jhon's</span><spanclass="pre">ESP32</span><spanclass="pre">Thing</span></code>. If not set, <codeclass="docutils literal notranslate"><spanclass="pre">hostname</span></code> will be used.</p></li>

<h3>mDNS Services<aclass="headerlink"href="#mdns-services"title="Permalink to this headline"></a></h3>
<p>mDNS can advertise information about network services that your device offers. Each service is defined by a few properties.</p>
<blockquote>
<div><ulclass="simple">
<li><p><codeclass="docutils literal notranslate"><spanclass="pre">instance_name</span></code>: friendly name for your service, like <codeclass="docutils literal notranslate"><spanclass="pre">Jhon's</span><spanclass="pre">EESP32</span><spanclass="pre">Web</span><spanclass="pre">Server</span></code>. If not defined, <codeclass="docutils literal notranslate"><spanclass="pre">default_instance</span></code> will be used.</p></li>
<li><p><codeclass="docutils literal notranslate"><spanclass="pre">service_type</span></code>: (required) service type, prepended with underscore. Some common types can be found <aclass="reference external"href="http://www.dns-sd.org/serviceTypes.html">here</a>.</p></li>
<li><p><codeclass="docutils literal notranslate"><spanclass="pre">proto</span></code>: (required) protocol that the service runs on, prepended with underscore. Example: <codeclass="docutils literal notranslate"><spanclass="pre">_tcp</span></code> or <codeclass="docutils literal notranslate"><spanclass="pre">_udp</span></code></p></li>
<li><p><codeclass="docutils literal notranslate"><spanclass="pre">port</span></code>: (required) network port that the service runs on</p></li>
<li><p><codeclass="docutils literal notranslate"><spanclass="pre">txt</span></code>: <codeclass="docutils literal notranslate"><spanclass="pre">{var,</span><spanclass="pre">val}</span></code> array of strings, used to define properties for your service</p></li>
</ul>
</div></blockquote>
<p>Example method to add a few services and different properties:</p>

<h3>mDNS Query<aclass="headerlink"href="#mdns-query"title="Permalink to this headline"></a></h3>
<p>mDNS provides methods for browsing for services and resolving host’s IP/IPv6 addresses.</p>
<p>Results for services are returned as a linked list of <codeclass="docutils literal notranslate"><spanclass="pre">mdns_result_t</span></code> objects.</p>
<spanclass="w"></span><spanclass="n">printf</span><spanclass="p">(</span><spanclass="s">"Host was not found!"</span><spanclass="p">);</span><spanclass="w"></span>
