您在這裡

這是第壹個字節為19，第二個字節在0 - 255之間，第三、第四字節可變動（下面為星號）的IP地址列表，表示為19.*.*.* (19.0.0.0 - 19.255.255.255)。

這個IP地址列表中包含256 * 256 * 256 = 16,777,216個IP地址，我們以其中壹個IP地址19.1.1.1為例，來描述這個IP的屬性：

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）。
