2. B類IP地址列表
B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,前兩段號碼(字節1.字節2)為網絡號碼,剩下的後兩段號碼(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,B類IP地址就由2字節的網絡地址和2字節主機地址組成,網絡地址的最高位必須是'10'。 B類IP地址範圍:128.0.0.0 ~ 191.255.255.255,可用IP地址範圍:128.0.0.1 ~ 191.255.255.254。 B類IP地址中網絡的標識長度為14位,主機標識的長度為16位,B類網絡地址適用於中等規模規模的網絡(2 ^ 14 = 16384個),每個網絡所能容納6萬多臺計算機(2 ^ 16 - 2 = 65534個)。 如果您需要了解B類IP段更詳細的IP地址段信息,請點擊B類IP地址列表中的標題鏈接。
