121.81开头的IP是哪里的IP,IP地址列表: 121.81.*.* (121.81.0.* - 121.81.255.*)
这是第一个字节为121,第二个字节为81,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121.81.*.* (121.81.0.0 - 121.81.255.255)。
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121.81.1.1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。
关于IP地址2进制、10进制、16进制的说明 关于网络号、主机号及A/B/C/D/E类IP的说明内容:
1. 第一个IP地址例子
121.81.1.1是一个公开IP地址,使用者位于日本 东京 Chiyoda City,其用途是固定电话互联网服务提供商,类型是宽带/电缆/光纤。更多详情:121.81.1.1。
🔝 返回顶部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。
