Question

I am trying to make a TCP socket connection to an IP address. I can do this by directly parsing an IP address like this:

IPAddress ipAddress = IPAddress.Parse("192.168.1.123");
IPEndPoint remoteEP = new IPEndPoint(ipAddress, 80);
// Create a TCP/IP  socket.
Socket sender = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);  // This works!

However, I cannot figure out how to divine this IP address from a DNS string. I’ve tried every combination of the following:

IPAddress ipAddress = Dns.Resolve("www.mydns.org");   // No dice
IPAddress ipAddress = Dns.GetHostEntry("www.mydns.org");  // Nada
IPAddress ipAddress = IPAddress.Parse(Dns.Resolve("www.mydns.org"));   // So many errors...
IPAddress ipAddress = IPAddress.Parse(Dns.Resolve("www.mydns.org").toString());  // WTh is this attempt anyway?

Would any of you kind souls have a tip to help me squeeze an IPAddress out of a DNS?

Answer 1

foreach (IPAddress ip in Dns.GetHostAddresses("www.mydns.org"))
{
    Console.WriteLine(ip.ToString());
}

or simply IPAddress address = Dns.GetHostAddresses("www.mydns.org")[0]; if you want the first one only.
