IP位址中224-256開頭的位址代表何意義?
 

:on_47:如題:

class A IP:1.0.0.1-126.255.255.254
class B IP:128.1.0.1-191.255.255.254
class C IP:192.0.0.1-223.255.254.254

那224.0.0.1-255.255.255.254的位址是做什的??

Class D 224.0.0.0~239.255.255.255 for multicast
Class E 240.0.0.0~255.255.255.255 reserved

class d 是實驗用群播ip
class e 是保留用ip
