<header><strong>What is local-ip.sh?</strong></header>
<main>
<article>local-ip.sh is a magic domain name that provides wildcard DNS for any IP address. It is heavily
inspired by <a href="http://local-ip.co">local-ip.co</a>, <a
href="https://sslip.io">sslip.io</a>, and <a href="https://xip.io">xip.io</a>.</article>
<article>Quick example, say your LAN IP address is <strong>192.168.1.10</strong>. Using
local-ip.sh,<br /><br />
<pre> <strong>192.168.1.10</strong>.local-ip.sh resolves to 192.168.1.10
dots.<strong>192.168.1.10</strong>.local-ip.sh resolves to 192.168.1.10
dashes.<strong>192-168-1-10</strong>.local-ip.sh resolves to 192.168.1.10</pre>
</article>
<article>...and so on. You can use these domains to access virtual hosts on your development web server
from devices on your local network. No configuration required!</article>
<article>The best part is, you can serve your content over HTTPS with our TLS certificate for
<code>*.local-ip.sh</code>:<ul>
<li><a href="/server.pem">server.pem</a></li>
<li><a href="/server.key">server.key</a></li>
</ul>Be aware that wildcard certificates are not recursive, meaning they don&#x27;t match
&quot;sub-subdomains&quot;. <br />In our case, this certificate will only match subdomains of
<code>local-ip.sh</code> such as <code>192-168-1-10.local-ip.sh</code> where dashes separate
the numbers that make up the IP address.</article>

<section>
<header><strong>How does it work?</strong></header>
<main>
<article>
local-ip.sh runs publicly a <a href="https://git.capsulecorp.dev/mokhtar/local-ip.sh">custom DNS server</a>.
When your computer looks up a local-ip.sh domain, the local-ip.sh DNS server resolves to the IP address it extracts from the domain.
</article>
<article>
The TLS certificate is obtained from Let&#x27;s Encrypt and renewed up to a month before it expires.
