This is a reactive solution to the problem.  Though there are times
when the only solution you have is to attempt to quell the problem
through a plethora of ugly ip route statements, I hardly think it is
a good solution to the problem.  Any person looking to harm your network
with intent greater than that of a passing whim would probably decide
to change his/her ip address after realizing that a host suddenly became
unreachable.
