Step 1: Start a new Console project in your Visual Studio.
Step 2: Add a namespace in your project as in the following:
Using System.Net;
Step 3: Before fetching the IP Address we need to know whose IP Address we really want. It's quite understood that we want our own PC. But, that must be specified in my code because computers are dumb.
So, we can fetch the machine Name (or Host Name) by the GetHostName() Method. And this is inside the Dns class.
Step 4: We are now ready to get the IP address of the Host.
For this we need to use the GetHostByName() method followed by AddressList array (first Index).
And, in GetHostByName's argument we "host name".
Then, our code looks like:
using System;  
using System.Collections.Generic;  
using System.Linq;  
using System.Text;  
using System.Net; //Include this namespace  
   
   
namespace IpProto  
{  
    class Program  
    {  
        static void Main(string[] args)  
        {   
            string hostName = Dns.GetHostName(); // Retrive the Name of HOST  
            Console.WriteLine(hostName);  
           // Get the IP  
            string myIP = Dns.GetHostByName(hostName).AddressList[0].ToString();  
            Console.WriteLine("My IP Address is :"+myIP);  
            Console.ReadKey();  
        }  
    }  
}
