Dziwna odpowiedź, gdy wysyłam ping xxx255

To jest konfiguracja sieci mojego komputera:

C:\Users\user>ipconfig

Windows IP Configuration

Ethernet adapter Local Area Connection:

   Connection-specific DNS Suffix  . :
   Link-local IPv6 Address . . . . . : fe80::f56e:2272:8e45:d325%11
   IPv4 Address. . . . . . . . . . . : 10.0.0.81
   Subnet Mask . . . . . . . . . . . : 255.255.255.0
   Default Gateway . . . . . . . . . : 10.0.0.60

Pytanie brzmi: dlaczego, kiedy jestem pingadresem IP 10.0.0.255, widzę następujący wynik:

C:\Users\User>ping 10.0.0.255

Jak widać powyżej, zamiast nic nie zwracać (ponieważ 10.0.0.255nie jest to prawidłowy adres IP i jest to adres IP mojej sieci), pinguje 10.0.0.5i 10.0.0.154! Dlaczego?

Zauważ, że sprawdziłem hostsplik pod Windows\system32\drivers\etc\ścieżką i jak widzisz, nie ma tam przekierowania:
