IPIP 地址列表: 251.221.*.* (251.221.0.* - 251.221.255.*)
這是第壹個字節為251，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251.221.*.* (251.221.0.0 - 251.221.255.255)。
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251.221.1.1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。

1. 第一個 IP 地址示例
圖標/圖像含義表
251.221.1.1是一個保留的IP地址。保留的IP地址段不會在互聯網上使用，因此與廣域網相連的路由器在處理保留IP地址時，只是將該數據包丟棄處理，而不會路由到廣域網上去。從而將保留IP地址產生的數據隔離在局域網內部。更多詳情：251.221.1.1。
🔝 回到頂部2. E類IP地址列表
E類地址的前4位恒為1111，預置前4位為1意味著E類地址開始於128 + 64 + 32 + 16 = 240。 E類IP地址範圍：240.0.0.0 ~ 255.255.255.255。 E類IPv4地址不區分網絡地址與主機地址。 E類IP地址保留為以後使用，通常用於研究之用。因此Internet上沒有可用的E類地址。 如果您需要了解E類IP地址段詳情，可以點擊E類IP地址列表中的標題鏈接。
