It forces you to leave the comfort of text-based protocols like HTTP and JSON and dive into the world of bits, bytes, and packed binary structures.</p> <p>This project is a <strong>Go</strong> implementation of a DNS server. We will implement the core of the Domain Name System protocol as defined in <a href="https://datatracker.ietf.org/doc/html/rfc1035"><code>RFC 1035</code></a>, handling everything from parsing raw UDP packets to constructing compliant responses.</p>
