Application samples
• Explanation of the entry Gateway, using PC A as an sample: PC A has the IP address 10.16.2.8 with a
subnet mask 255.255.255.0. This means that it can reach all IP telegrams within a range from
10.16.2.0 to 10.16.2.255. If it is required to send an IP telegram to a different address range (e.g. to
192.168.1.1), this must run via the defined gateway, in this case 10.16.2.21, which in turn can relay the
telegram to 192.168.1.10 via the configured IP routing.
• Windows offers the useful command line command ipconfig for checking the configuration. If PC A is
configured correctly, the command Start Run cmd ipconfig/all displays the following screen:

• IP routing is disabled (default) and the IP address of the selected adaptor (here called LAN) is
assigned fixedly. Since DHCP was set beforehand, WINS entries are still present.
• The same command on PC C displays:
