Yes,yes,yes. If the router is not on a class C subnet it can
possibly have a 0 or 255 as the last number. But that is more than
likely not the case in a home device.

And of course I should have said 'in the last octet', IP addresses
can most definitely have a 0 or 255 in the first 3 octets. I stand
corrected.

What I should have said was 192.168.2.0 or 192.168.2.255 are
impossible addresses for a home setup.
