251.140.56开头的IP是哪里的IP,IP地址列表: 251.140.56.* (251.140.56.0 - 251.140.56.254)

这是第一个字节为251，第二个字节为140，第三个字节为56，第四个字节在0 - 255之间的IP地址列表，表示为251.140.56.* (251.140.56.0 - 251.140.56.255)。

这个IP地址列表中包含256个IP地址，我们以其中一个IP地址251.140.56.1为例，来描述这个IP的属性：

251.140.56.1是一个保留的IP地址。保留的IP地址段不会在互联网上使用，因此与广域网相连的路由器在处理保留IP地址时，只是将该数据包丢弃处理，而不会路由到广域网上去。从而将保留IP地址产生的数据隔离在局域网内部。更多详情：251.140.56.1。

E类地址的前4位恒为1111，预置前4位为1意味着E类地址开始于128 + 64 + 32 + 16 = 240。

E类IP地址范围：240.0.0.0 ~ 255.255.255.255。

E类IPv4地址不区分网络地址与主机地址。

E类IP地址保留为以后使用，通常用于研究之用。因此Internet上没有可用的E类地址。
