CIDR还能非常灵活地支持对(IP 地址中的)网络号进行子网划分,划分出来的子网可分配给不同的组织,以实现域间路由信息的交换。比如,可将地址块 131.108.0.0/16 划分为 4 个“二级”地址块(131.108.0.0/18、131.108.64.0/18、131.108.128.0/18和 131.108.192.0/18),然后,再分配给4个不同的组织。
Internet Protocol version 4 was released in 1983, and is the standard for all packet-switch-based networks in use today. IPv4 uses a 32-bit address space that gives an upper limit of 4,294,967,296 (4.3 billion) unique logical IP addresses. A large number of these available IP addresses...
