221.123开头的IP是哪里的IP,IP地址列表: 221.123.*.* (221.123.0.* - 221.123.255.*)
这是第一个字节为221,第二个字节为123,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221.123.*.* (221.123.0.0 - 221.123.255.255)。
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221.123.1.1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. C类IP地址列表
C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,前三段号码(字节1.字节2.字节3)为网络号码,剩下的后一段号码(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,C类IP地址就由3字节的网络地址和1字节主机地址组成,网络地址的最高位必须是'110'。 C类IP地址范围:192.0.0.0 ~ 223.255.255.255,可用IP地址范围:192.0.0.1 ~ 223.255.255.254。 C类IP地址中网络的标识长度为21位,主机标识的长度为8位,C类网络地址数量较多(2 ^ 21 = 2097152个),适用于小规模的局域网络,每个网络最多只能包含254台计算机(2 ^ 8 - 2 = 254个)。 如果您需要了解C类IP地址段详情,可以点击C类IP地址列表中的标题链接。
