It's not a "broadcast subnet mask" but a host subnet mask. Basically it
tells you the route is just for that host and no other (all bits of the
ip address must match for the route to be used).

What is the gateway to this particular route? If you do a
tracepath (or traceroute or tracert) where does it go through?
