The way these MyPLC hosts are setup, is that they have multiple subinterfaces, each configured to be part of a different IP subnet. Almost all subnets in the hosts are in the form of 10.42.Y.0/24. You will notice that for all these subnets, your host has the same last octet. In the example above all the subinterfaces of eth1, will have an IP address that will end in '''90''' (10.42.147.'''90''', 10.42.148.'''90''')105 i.
