1. 第一個 IP 地址示例

251.139.186.1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:251.139.186.1。
🔝 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。
