I have the host computer with Ethernet adapter configured by this way: IP address 192.170.100.10, subnet mask 255.255.255.0. There is also hardware device which works like IP server, configured as: 192.170.100.20, 255.255.255.0. When I connect this device to the host Ethernet adapter, the following information is added to route print
command output (Windows):
Active Routes: Network Destination Netmask Gateway Interface Metric 192.170.100.0 255.255.255.0 192.170.100.10 192.170.100.10 20 192.170.100.10 255.255.255.255 127.0.0.1 127.0.0.1 20 192.170.100.255 255.255.255.255 192.170.100.10 192.170.100.10 20
I need some explanation of this output: how these entries are added, how they are used to route network packets 192.170.100.* to this adapter.
Means that anything on the 192.170.100.0 network will use 192.170.100.10 as it's gateway
Means that anything looking for 192.170.100.10 will actually get sent to the loopback (local) address.
Is the broadcast address for the 192.170.100.0 network.
Line 1: Send everything that goes to 192.170.100.* out via your network card at 192.170.100.10, if no rule exists, that is more special
Line 2: Send packets to yourself NOT via cour network card, but via Loopback
Line 3: Send broadcasts via your network card.
As there is no rule for anything other than 192.170.100.* you will not be able to reach other nets
