I have the host computer with Ethernet adapter configured by this way: IP address

  • 0

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.

    192.170.100.0    255.255.255.0   192.170.100.10  192.170.100.10       20

    Means that anything on the 192.170.100.0 network will use 192.170.100.10 as it’s gateway

    192.170.100.10  255.255.255.255        127.0.0.1       127.0.0.1       20

    Means that anything looking for 192.170.100.10 will actually get sent to the loopback (local) address.

    192.170.100.255  255.255.255.255   192.170.100.10  192.170.100.10       20

    Is the broadcast address for the 192.170.100.0 network.
