This is my implementation in Go for the "Build Your Own DNS Server" Challenge

Primary LanguageGo

This is a starting point for Go solutions to the "Build Your Own DNS server" Challenge.

In this challenge, you'll build a DNS server that's capable of parsing and creating DNS packets, responding to DNS queries, handling various record types and doing recursive resolve. Along the way we'll learn about the DNS protocol, DNS packet format, root servers, authoritative servers, forwarding servers, various record types (A, AAAA, CNAME, etc) and more.

Note: If you're viewing this repo on GitHub, head over to codecrafters.io to try the challenge.

Passing the first stage

The entry point for your your_program.sh implementation is in app/main.go. Study and uncomment the relevant code, and push your changes to pass the first stage:

git add .
git commit -m "pass 1st stage" # any msg
git push origin master

Time to move on to the next stage!

Stage 2 & beyond

Note: This section is for stages 2 and beyond.

  1. Ensure you have go (1.19) installed locally
  2. Run ./your_program.sh to run your program, which is implemented in app/main.go.
  3. Commit your changes and run git push origin master to submit your solution to CodeCrafters. Test output will be streamed to your terminal.
