If some unfortunate soul does get 1.1.1.1, 1.2.3.4, 1.3.3.7, etc, they
would also likely experience significant global reachability problems in
addition to all of the unintended noise that gets sent their way.
There are many sites that specifically filter those addresses, in
addition to those that don't update bogon filters, or assume "no one
will _ever_ get 1.2.3.4!" :)
