PACSystems以太网接口支持“超设置”,这是一种配置子网掩码以允许与多个子网通信的技术。由此产生的超网是一个被寻址为单个子网的连续子网块。子网寻址和子网掩码子网寻址是IP地址方案的扩展,允许站点对多个物理网络使用单个netid。通过类将IP地址划分为netid和hostid,站点外的路由照常进行。B类网络中IP地址的netid位和hostid位的标准格式如下所示。在站点内部,子网掩码用于将IP地址重新划分为自定义netid部分和hostid部分。考虑在前面的示例中向网络2(B类网络)添加另一个物理网络。结果如下图所示。选择下面显示的子网掩码将添加两个额外的netid位,允许寻址为0、64、128和192的四个物理网络。添加的子网位通常取自与netid相邻的hostid位,子网掩码标识这些位。子网掩码中的位与Internet地址一一对应。掩码中为1的比特将IP地址中的相应比特视为netid比特的一部分。掩码中为0的位将相应的位视为主机ID位的一部分
PACSystems Ethernet interfaces support “supernetting,” a technique of configuring the subnet mask to allow communication to multiple subnets. The resulting supernet is a block of contiguous subnets addressed as a single subnet.Subnet Addressing and Subnet Masks Subnet addressing is an extension of the IP address scheme that allows a site to use a single netid for multiple physical networks. Routing outside the site continues as usual by dividing the IP address into a netid and a hostid via the class. The standard format for the netid bits and hostid bits for an IP address in a Class B network is shown below.Inside a site the subnet mask is used to re-divide the IP address into a custom netid portion and hostid portion. Consider adding another physical network to Network 2 (a Class B network) in the previous example. The result is shown in the figure below. Selecting the subnet mask shown below would add two additional netid bits allowing for four physical networks addressed as 0, 64, 128, and 192. The added subnet bits are normally taken from the hostid bits adjacent to the netid and the subnet mask identifies these bits.The bits in the subnet mask correspond one to one with the Internet address. The bits in the mask that are 1 treat the corresponding bits in the IP address as part of the netid bits. The bits in the mask that are 0 treat the corresponding bits as part of the hostid bits
