+Building a DNS server in Rust
+=============================
+
+To me, DNS is one the most exciting aspects of the Internet. Before it was
+invented, everyone on the internet - which admittedly wasn't that many at that
+stage - relied on a shared file called HOSTS.TXT, maintained by the Stanford
+Research Institute. This file was synchronized manually through FTP, and as the
+number of hosts grew, so did the rate of change and the unfeasibility of the
+system. In 1983, Paul Mockapetris set out to find a long term solution to the
+problem and went on to design and implement DNS. It's a testament to his
+genius that the his creation has been able to scale from a few thousand
+computers to the Internet as we know it today.
+
+With the combined goal of gaining a deep understanding of DNS, of doing
+something interesting with Rust, and of scratching some of my own itches,
+I originally set out to implement my own DNS server. This document is not
+a truthful chronicle of that journey, but rather an idealized version of it,
+without all the detours I ended up taking. We'll gradually implement a full
+DNS server, starting from first principles.
