How to obtain the ipv6 address in Xamarin app ?

I want to get the Ipv6 address of my Android or iOS device using the Xamarin Forms app.
How can I do it?

Try to get the ip address on each platform and then use DependencyService to call the method to obtain the value in the shared project.

For example, get the ipv6 address on Android platform:

   [assembly: Xamarin.Forms.Dependency(typeof(TestImplementation))]  
   namespace TestApplication_5.Droid  
   {  
       public class TestImplementation : ITestInterface  
       {  
           public string getIPv6Address()  
           {  
               try  
               {  
                   for (var en = NetworkInterface.NetworkInterfaces; en.HasMoreElements;)  
                   {  
                       NetworkInterface intf = en.NextElement() as NetworkInterface;  
                       for (var enumIpAddr = intf.InetAddresses; enumIpAddr.HasMoreElements;)  
                       {  
                           InetAddress inetAddress = enumIpAddr.NextElement() as InetAddress;  
                           if (!inetAddress.IsLoopbackAddress && inetAddress.GetType() == typeof(Inet6Address))  
                           {  
                               string ipaddress = inetAddress.HostAddress.ToString();  
                               return ipaddress;  
                           }  
                       }  
                   }  
               }  
               catch (Exception)  
               {  
     
               }  
               return null;  
           }  
       }   
   }  
     
   //obtain the address in the shared project  
   var address = DependencyService.Get<ITestInterface>().getIPv6Address();

I couldn't find a method to get the ipv6 address on iOS. Can you please share the namespaces that you have used?
