IP19.120开头的IP是哪里的IP,IP地址列表: 19.120.*.* (19.120.0.* - 19.120.255.*)
这是第一个字节为19，第二个字节为120，第三个字节在0 - 255之间，第四字节可变动（下面为星号）的IP地址列表，表示为19.120.*.* (19.120.0.0 - 19.120.255.255)。
这个IP地址列表中包含256 * 256 = 65,536个IP地址，我们以其中一个IP地址19.120.1.1为例，来描述这个IP的属性：
但这只是其中1个IP地址的例子，并不代表这个列表中所有的IP地址都有同样的属性，如果需要了解其它IP和更详细的IP地址段信息，请点击下面列表中的标题链接。

2. A类IP地址列表
A类IP地址是指：在IP地址的四段号码（例如：字节1.字节2.字节3.字节4）中，第一段号码（字节1）为网络号码，剩下的后三段号码（字节2.字节3.字节4）为本地计算机的号码。 如果用二进制表示IP地址的话，A类IP地址就由1字节的网络地址和3字节主机地址组成，网络地址的最高位必须是'0'。 A类IP地址范围：1.0.0.0 ~ 127.255.255.255，可用IP地址范围：1.0.0.1 ~ 127.255.255.254。 A类IP地址中网络的标识长度为7位，主机标识的长度为24位，A类网络地址数量较少（2 ^ 7 - 2 = 126个），可以用于容纳1600多万计算机的大型网络（2 ^ 24 - 2 = 16777214个）。 如果您需要了解A类IP段更详细的IP地址信息，请点击A类IP地址列表中的标题链接。
