2. A類IP地址列表
A類IP地址是指:在IP地址的四段號碼(例如:字節1.字節2.字節3.字節4)中,第壹段號碼(字節1)為網絡號碼,剩下的後三段號碼(字節2.字節3.字節4)為本地計算機的號碼。
如果用二進制表示IP地址的話,A類IP地址就由1字節的網絡地址和3字節主機地址組成,網絡地址的最高位必須是'0'。
A類IP地址範圍:1.0.0.0 ~ 127.255.255.255,可用IP地址範圍:1.0.0.1 ~ 127.255.255.254。
A類IP地址中網絡的標識長度為7位,主機標識的長度為24位,A類網絡地址數量較少(2 ^ 7 - 2 = 126個),可以用於容納1600多萬計算機的大型網絡(2 ^ 24 - 2 = 16777214個)。
