Sounds like netstat has the same bug that netstat -M had -- not printing out 
netmasks ends up making you guess what netmask is stored in the kernel, 
meaning that you will probably guess what you expect instead of what is there.

Between the time that I discovered the bug and the time that we went to host 
routes for multicast, I printed out subnets as "x.y.z/n", where n is the 
number of 1-bits in the netmask.  It adds at most 3 characters to the address, 
and perhaps a "/32" could be left off, to optimize for host-routes.

If nobody does this by the time I get around to fixing netstat -M, I will do 
it.
