Contoh

Contoh kode berikut menampilkan nilai properti ini.

void ShowIPStatistics()
{
   IPGlobalProperties ^ properties = IPGlobalProperties::GetIPGlobalProperties();
   IPGlobalStatistics ^ ipstat = properties->GetIPv4GlobalStatistics();
   Console::WriteLine( "  Forwarding enabled ...................... : {0}", 
      ipstat->ForwardingEnabled );
   Console::WriteLine( "  Interfaces .............................. : {0}", 
      ipstat->NumberOfInterfaces );
   Console::WriteLine( "  IP addresses ............................ : {0}", 
      ipstat->NumberOfIPAddresses );
   Console::WriteLine( "  Routes .................................. : {0}", 
      ipstat->NumberOfRoutes );
   Console::WriteLine( "  Default TTL ............................. : {0}", 
      ipstat->DefaultTtl );
}

public static void ShowIPStatistics()
{
    IPGlobalProperties properties = IPGlobalProperties.GetIPGlobalProperties();
    IPGlobalStatistics ipstat = properties.GetIPv4GlobalStatistics();
    Console.WriteLine("  Forwarding enabled ...................... : {0}",
        ipstat.ForwardingEnabled);
    Console.WriteLine("  Interfaces .............................. : {0}",
        ipstat.NumberOfInterfaces);
    Console.WriteLine("  IP addresses ............................ : {0}",
        ipstat.NumberOfIPAddresses);
    Console.WriteLine("  Routes .................................. : {0}",
        ipstat.NumberOfRoutes);
    Console.WriteLine("  Default TTL ............................. : {0}",
        ipstat.DefaultTtl);
}

Public Shared Sub ShowIPStatistics() 
    Dim properties As IPGlobalProperties = IPGlobalProperties.GetIPGlobalProperties()
    Dim ipstat As IPGlobalStatistics = properties.GetIPv4GlobalStatistics()
    Console.WriteLine("  Forwarding enabled ...................... : {0}", ipstat.ForwardingEnabled)
    Console.WriteLine("  Interfaces .............................. : {0}", ipstat.NumberOfInterfaces)
    Console.WriteLine("  IP addresses ............................ : {0}", ipstat.NumberOfIPAddresses)
    Console.WriteLine("  Routes .................................. : {0}", ipstat.NumberOfRoutes)
    Console.WriteLine("  Default TTL ............................. : {0}", ipstat.DefaultTtl)

End Sub

Keterangan

Nilai TTL dilaporkan sebagai jumlah simpul perutean yang dapat meneruskan paket sebelum dibuang. Setiap simpul mengurangi nilai TTL saat ini dalam paket sebelum meneruskannya. Jika nilai TTL mencapai nol, paket dianggap tidak dapat dikirim dan dibuang. Perhatikan bahwa ketika paket melakukan perjalanan dari satu simpul ke simpul lain, ini juga dikenal sebagai "hop".
