I develop a network project so want to view all ip address

// Get host name
String strHostName = Dns.GetHostName();

// Find host by name
IPHostEntry iphostentry = Dns.GetHostByName(strHostName);

// Enumerate IP addresses
int nIP = 0;
foreach(IPAddress ipaddress in iphostentry.AddressList)
{
   
}

OR 


foreach (NetworkInterface netInterface in NetworkInterface.GetAllNetworkInterfaces())
  {
    Console.WriteLine("Name: " + netInterface.Name);
    Console.WriteLine("Description: " + netInterface.Description);
    Console.WriteLine("Addresses: ");
    IPInterfaceProperties ipProps = netInterface.GetIPProperties();
    foreach (UnicastIPAddressInformation addr in ipProps.UnicastAddresses)
    {
      Console.WriteLine(" " + addr.Address.ToString());
    }
    Console.WriteLine("");
  }
