I have been ask to write a test tool which initiates DNS-HTTP-HTTPS-TCP

For HTTP I used std.net like "m_HTTP = HTTP(m_url);m_HTTP.perform();"
For DNS I simply used "getAddressInfo(m_domainName);"
Than tool makes some simple checks which are npt subjects of this
thread and the tool works well,
But now I need to make an improvement. I need to get sourceIP(ip which
program runs), sourcePort( eg: 53212 not 80), destIP, destPort(most
probably 80) from the session which I initiated.
I need functions like std.socket.localAddress, std.socket.remoteAddress
for HTTP-DNS but couldn't managed to find them.
Is there any way that I can get socket info in HTTP and DNS sessions
which I initiated?

std.net is implemented in terms of libcurl but does not expose all of
its functionality. I could not find a way of extracting curl-related
information from it.
I found the following Socket example in my stash of code where it's easy
to get the address information with remoteAddress() and localAddress().
But of course Socket is lower level than std.net. :-/
import std.stdio;
import std.socket;
void main() {
Socket server = new TcpSocket();
server.setOption(SocketOptionLevel.SOCKET, SocketOption.REUSEADDR,
true);
server.bind(new InternetAddress(8080));
server.listen(1);
while(true) {
Socket client = server.accept();
writefln("client Socket connected on %s", client.remoteAddress);
char[1024] buffer;
auto received = client.receive(buffer);
writefln("The client said:\n%s", buffer[0.. received]);
enum header =
"HTTP/1.0 200 OK\nContent-Type: text/html; charset=utf-8\n\n";
string response = header ~ "Hello World!\n";
client.send(response);
client.shutdown(SocketShutdown.BOTH);
client.close();
}
}
