I don't see the point of enforcing strictness here. There are good use
cases: if you know your address is 82.94.164.162, how do you compute
what you should spell for 82.94.164.162/27? It's very easy to make a
mistake here, and doing the computation in your head is really not
something that should be necessary, given that a computer can get it
correct easily.
