This looks reasonable to me, although it would be nicer if
applications wouldn't even notice that the IP-address has changed,
but I guess this is not really that easy to handle:-/ What is an
application excpected to do, when it get's such a message, in
whatever way? Should it shutdown all the connections it maintains
and reestablish them if/when a new IP-address is available? Is
there still time for the application to shutdown, because it will
get this message when the IP-address has already expired? How do
other OS' and the applications thereon handle this?
