A simple, built-in trick is to use <code>/etc/hosts</code> to map an IP address to a friendly hostname so your tools, browser, and shell can use a memorable name.</p> <p>Example mapping:</p> <pre tabindex="0"><code>10.82.186.54 cybershield.nc3 </code></pre><p>This lets you visit <code>http://cybershield.nc3</code> in your browser, curl <code>cybershield.nc3</code>, and point tools at the hostname instead of the IP.</p> <p><strong>What /etc/hosts Does</strong></p> <ul> <li>Local override: Maps hostnames to IPs before DNS is queried.</li> <li>Zero dependencies: No DNS server required; works offline.</li> <li>System-wide: Applies to all applications on the machine.</li> </ul> <p><strong>How to Add an Entry (macOS/Linux)</strong></p>
