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();
     }
}
