Listen on more socket types #155
Description
Currently, ncdns listens on a DNS over UDP socket and a DNS over TCP socket (grep that file for "tcp" and "udp"). It would be helpful to support more socket types, such as:
- DNS over TLS
- DNS over DTLS
- DNS over QUIC
- DNS over HTTP(S)
- DNS over Unix domain socket
- DNS over Windows named pipe
- DNSCurve
