A straightforward DNS resolution library for integration with DoT (DNS over TLS) and DoH (DNS over HTTPS).
Warning
The current version of this library only supports querying A and AAAA records. For CNAME records, the Status value in the DnsResolveResult class will be CNameRedirect.
To facilitate integration, a simple method is provided. You just need to set the ConnectCallback of SocketsHttpHandler as follows:
ConnectCallback = async (context, cts) => await HttpConnectCallback.GetNetworkStream(context, cts);The GetNetworkStream method selects the optimal IP address based on the RFC 8305 (Happy Eyeballs) algorithm and establishes a TCP connection.
Next, configure the DoTClient.DoTAddress or DoHClient.DoHAddress according to whether you're using a DoT or DoH server.
By default, the DoTClient uses port 853 for establishing connections to DoT servers. If your DoT server operates on a different port, adjust the DoTClient.Port property accordingly.
For detailed instructions on how to perform DoT and DoH queries within the library itself, please refer to the Wiki.
