> Simple DNS Forwarder
> [!IMPORTANT]
> Work In Progress ...
## Todo
- [ ] concurrent connections
- [ ] mapping response to client
- [ ] caching
- [ ] support for falling back to different dns server
## Demo
> DNS forwarding server
> The client requests the DNS forwarding server (running at localhost:8989) to resolve the address of the domain name "www.google.com"
## Quick start
- Build the project using `make`
- Run the DNS forwarding server using `./server`
- Test the server using a dummy client via `make client`
