实际上,B类主机ID的两位已被用于扩展netid,从而创建一个扩展的netid或子网。主机ID中子网掩码位为1的部分中的每个的位组合指定不同的物理网络。13.3.2示例:分为两个子网的网络将网络2分为子网2.1和2.2的新网络配置如图110所示。这里添加了第二个具有主机D和E的网络。网关G2连接子网2.1和子网2.2。主机D和E将使用网关G2与不在网络2.2上的主机进行通信。主机B和C将使用网关G1和G2与不在网络2.1上的主机进行通信。当B与D通信时,G2(为B配置的网关)将通过网关G2将数据从B路由到D。主机A将使用网关G1与不在网络1上的主机通信。示例:两个网络合并为一个超级网络超级网络是一种通过扩展子网掩码的主机部分并减少网络部分来将两个较小的网络合并为较大网络的技术。超级网络仅适用于共享相同网络id值的相邻网络,例如本例中的网络1和2(图112)。与子网一样,子网掩码用于将IP地址划分为自定义netid部分和hostid部分。
In effect, two bits of the Class B hostid have been used to extend the netid, creating an extended netid, or subnetid. Each unique combination of bits in the part of the hostid where subnet mask bits are 1 specifies a different physical network. 13.3.2 Example: Network Divided into Two Subnets The new network configuration dividing Network 2 into Subnets 2.1 and 2.2 is shown in Figure 110.Here, a second network with Hosts D and E has been added. Gateway G2 connects Subnet 2.1 with Subnet 2.2. Hosts D and E will use Gateway G2 to communicate with hosts not on Network 2.2. Hosts B and C will use Gateways G1 and G2 to communicate with hosts not on Network 2.1. When B is communicating with D, G2 (the configured Gateway for B) will route the data from B to D through Gateway G2. Host A will use Gateway G1 to communicate with hosts not on Network 1.Example: Two Networks Combined into a Supernet Supernetting is a technique used to combine two smaller networks into a larger network by extending the host portion of the subnet mask and reducing the network portion. Supernetting works only with adjacent networks that share the same network id value, such as networks 1 and 2 in this example (Figure 112). As with subnets, the subnet mask is used to divide the IP address into a custom netid portion and hostid portion.
