非标准子网的划分及子网掩码的确定

Division of Non-standard Subnet and Definition of Subnet Mark

网络IP地址资源的有限性使得无限膨胀的网络用户可享有的IP地址数目越来越少,子网的划分是解决这个问题的有效途径。常规方法构造的标准子网在网络ID和主机ID数目构造上受到限制,也不够灵活,因此采用非标准子网划分的方法可解决这个问题。

The limited numbers of IP address that can be supplied to increasingly infinite users are getting less and less. Effective method to resolve this problem is to create subnet. The regular standard subnet is limited and inflexible in network ID and host ID. By non-standard subnet division, the problem can be resolved.
