IPIP 地址列表: 199.81.*.* (199.81.0.* - 199.81.255.*)
這是第壹個字節為199，第二個字節為81，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199.81.*.* (199.81.0.0 - 199.81.255.255)。
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199.81.1.1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. C類IP地址列表
C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，前三段號碼（字節1.字節2.字節3）為網絡號碼，剩下的後壹段號碼（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，C類IP地址就由３字節的網絡地址和1字節主機地址組成，網絡地址的最高位必須是'110'。 C類IP地址範圍：192.0.0.0 ~ 223.255.255.255，可用IP地址範圍：192.0.0.1 ~ 223.255.255.254。 C類IP地址中網絡的標識長度為21位，主機標識的長度為8位，C類網絡地址數量較多（2 ^ 21 = 2097152個），適用於小規模的局域網絡，每個網絡最多只能包含254臺計算機（2 ^ 8 - 2 = 254個）。 如果您需要了解C類IP地址段詳情，可以點擊C類IP地址列表中的標題鏈接。
