DNS is a rather enigmatic protocol, but it is a key piece of our modern life. After wrestling with some dns issues I decided learning more about the protocol and implementing it myself would be a fun project so I set to work using Rust!

This project made me significantly more comfortable working at the bit level and using bitwise operations.

Currently, the server can parse and resolve a domain for queries with A, NS, CNAME, MX, and AAAA records.
