with "-host" it still picks the default route.  
with "-netmask 0xffffffff" it gave me an error "Invalid
argument", which went away if I specified the address
before the "-netmask 0xffffffff" but it still picks the
default route. Output is attached below.

;	any differences if you add "-host" or "-netmask"?
