产品详细资料
当IP地址为172.17.0.1的主机B与主机C通信时,它从C的IP地址中知道C在同一网络上。在以太网环境中,B可以将C的IP地址解析为MAC地址(通过ARP),并直接与C通信。当主机B与主机A通信时,它从A的IP地址中知道A在另一个网络上(网络ID不同)。为了向A发送数据,B必须具有连接两个网络的网关的IP地址。在本例中,网关在网络2上的IP地址为172.17.0.3。该地址将在PLC B的以太网接口模块配置中配置为其默认网关地址。请注意,网关有两个IP地址(172.16.0.2和172.17.0.3)。个IP地址必须由网络1上的主机使用,第二个IP地址则必须由网络2中的主机使用。为了可用,主机的网关必须使用与自己的netid匹配的IP地址进行寻址。子网和超级网子网允许站点的网络管理员将一个大型网络划分为几个较小的网络,同时仍然将整个网络作为一个单一的实体向外部世界展示。站点的每个内部网关只需要维护其他内部网关的子网编号,而不需要维护整个网络上的每个主机。
When host B with IP address 172.17.0.1 communicates with host C, it knows from C’s IP address that C is on the same network. In an Ethernet environment, B can then resolve C’s IP address to a MAC address (via ARP) and communicate with C directly. When host B communicates with host A, it knows from A’s IP address that A is on another network (the netids are different). In order to send data to A, B must have the IP address of the gateway connecting the two networks. In this example, the gateway’s IP address on Network 2 is 172.17.0.3. This address would be configured in the Ethernet interface’s module configuration for PLC B as its default gateway address. Note that the gateway has two IP addresses (172.16.0.2 and 172.17.0.3). The first must be used by hosts on Network 1 and the second must be used by hosts on Network 2. To be usable, a host’s gateway must be addressed using an IP address with a netid matching its own.Subnets and Supernets Subnets allow a site’s network administrators to divide a large network into several smaller networks while still presenting the overall network as one single entity to the outside world. Each of the site’s interior gateways need only maintain the subnet numbers of other interior gateways instead of every single host on the entire network.
