Can anyone tell me what is difference between Internal IP Address and External IP Address? How to get both in any programming language like Java, C# or Adobe AIR?

推荐答案

内部IP地址是网络中的地址：

Internal IP address is the address from your network:

IPHostEntry heserver = Dns.GetHostEntry(Dns.GetHostName());
IPAddress curAdd = heserver.AddressList[0];
curAdd.ToString();

您的外部IP地址是您ISP的地址

Your external IP address is the address from your ISP

string ip = new 
     System.Net.WebClient()
      .DownloadString(("http://www.whatismyip.com/automation/n09230945.asp"));
