IPIP 地址列表: 168.221.*.* (168.221.0.* - 168.221.255.*)
這是第壹個字節為168，第二個字節為221，第三個字節在0 - 255之間，第四字節可變動（下面為星號）的IP地址列表，表示為168.221.*.* (168.221.0.0 - 168.221.255.255)。
這個IP地址列表中包含256 * 256 = 65,536個IP地址，我們以其中壹個IP地址168.221.1.1為例，來描述這個IP的屬性：
但這只是其中1個IP地址的例子，並不代表這個列表中所有的IP地址都有同樣的屬性，如果需要了解其它IP和更詳細的IP地址段信息，請點擊下面列表中的標題鏈接。

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。
