						<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
								dangerouslySetInnerHTML={{
									__html: `       <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`,
								}}
							/>
						</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't match
							"sub-subdomains". <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.

						<strong>How does it work?</strong>
					</header>
					<main>
						<article>
							local-ip.sh runs publicly a{" "}
							<a href="https://git.mokhtar.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's Encrypt and renewed up to a month before it
							expires.
