 Why do you want to have that? it is an invalid address.
 
 This also is a user question and not a problem, please defer to http://lists.freebsd.org/mailman/listinfo/freebsd-questions
 you might also want to take a look at freebsd-net and/or freebsd-hackers.
 
 I will close the PR. If people think that after discussing this on the mailinglist this is still a problem, please
 come back to me and I will reopen the ticket (and add any usefull information where needed).
 
 Thanks!
