This collaborative project is a toy DNS resolver written in C and based on Julia Evans' Implement DNS in a Weekend Python guide.

The program features DNSQuery, DNSHeader, DNSQuestion, and DNSRecord structs that maintain the various component parts of a DNS request and the parsed DNS response. At a high level, the program currently performs as follows:

1. open a socket fild descriptor using socket()
2. instantiate and populate a DNSQuery struct with details about the DNS request using constructor function NewDNSQuery()
3. send above DNSQuery struct using sendto()
4. receive response with recvfrom()
5. close socket file descriptor with `close()
6. parse response into DNSHeader, DNSQuestion, and DNSRecord structs

For working branch, see sendto.

The sandbox/ directory contains a number of DNS-related and DNS-adjacent experients and toy projects designed to improve intuition about networking in general and C's networking systems calls.
