 Hello, first if all thank you for the willingness to help!
 
 So what is the exact problem? that you forgot a word and the
 interface got something assigned which was not intended?
 
 If you would do a ifconfig rl0 www.freebsd.org, you would
 get www.freebsd.org assigned to rl0, if i'd use something
 like ifconfig em1 bleah and bleah does not exist it will
 let the current information say alive. If it did exist
 it would have assigned me that adress instead.
 
 Perhaps you can consider mailing the freebsd-net mailinglist
 the next time that you encounter such an issue since this
 feels like a user question instead of a problem.
 
 If i missed the point you tried to make, please elaborate
 so that I can try to figure who can help you etc.
 
 Thanks again!
 
 Cheers,
 Remko
