IPIP 地址列表: 112.21.*.* (112.21.0.* - 112.21.255.*)
這是第壹個字節為112，第二個字節為21，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112.21.*.* (112.21.0.0 - 112.21.255.255)。
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112.21.1.1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。

圖標/圖像含義表
112.21.1.1是一個公開IP地址，使用者位於中国 江苏省 无锡，其用途是固定電話互聯網服務提供商/手機互聯網服務提供商，類型是寬帶/電纜/光纖。更多詳情：112.21.1.1。
🔝 回到頂部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）。 如果您需要了解A類IP段更詳細的IP地址信息，請點擊A類IP地址列表中的標題鏈接。
