Let's tackle the Codecrafter's DNS server challenge in Go. In this challenge, we'll build a limited version of a DNS server to learn more about DNS queries, questions, answers, and how parse all of that. Additionally, we'll talk about compression patterns for queries and ultimately build support for forwarding queries to another DNS server. DNS is a protocol used to resolve domain names to IP addresses. In this challenge, you'll build a DNS server that's capable of responding to basic DNS queries. Along the way you'll learn about the DNS protocol, DNS packet format, DNS record types, UDP servers and more.
