<h4>How to verify DNS is encrypted</h4>

<ul>

<li>Check <a href="https://www.dnsleaktest.com/">DNSLeakTest.com</a>. <span class="badge badge-warning" data-toggle="tooltip" data-placement="bottom" data-original-title="Your DNS provider may not appear with their own name, so compare the responses to what you know or can find about your DNS provider. Just ensure you don't see your ISP or old unencrypted DNS provider."><i class="fas fa-exclamation-triangle"></i></span></li>
|
||||
<li>Check the website of your DNS provider. They may have a page for telling "you are using our DNS." Examples include <a href="https://adguard.com/en/adguard-dns/overview.html">AdGuard</a> and <a href="https://1.1.1.1/help">Cloudflare</a>.</li>
|
||||
<li>If using Firefox's trusted recursive resolver (TRR), navigate to <code>about:networking#dns</code>.
