Looking at the exact numbers again, it seems it is simpler than I
thought: the true netmask is just different from what you've been told.
If you set it to 255.255.254.0, both 200.2.116.140 and 200.2.117.1 will
be in the same network, and things should be correct.

Now if they have set up things such that you can't reach, say,
200.2.117.0.128 (which is outside the given netmask 255.255.255.240),
then they have truely messed up.
