IMPORTANT! Network is unreachable

Usually if there is more than IP in a given subnet on an interface, you 
give it a /32 netmask.  Only the first IP in a subnet should have the 
full netmask.

So your example should look like this:


     inet 10.11.16.14 netmask 0xffffff00 broadcast 10.11.16.255
     inet 10.11.16.9 netmask 0xffffffff broadcast 10.11.16.9
