209.81开头的IP是哪里的IP,IP地址列表: 209.81.*.* (209.81.0.* - 209.81.255.*)
这是第一个字节为209,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209.81.*.* (209.81.0.0 - 209.81.255.255)。
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209.81.1.1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
209.81.1.1是一个公开IP地址,使用者位于美国 加州 San Jose,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:209.81.1.1。
🔝 返回顶部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。
