1. 第一個 IP 地址示例
210.121.221.1是一個公開IP地址,使用者位於韩国 京畿道 城南市,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:210.121.221.1。
🔝 回到頂部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。
