Any network only has one host per ip address (although a host may be in 
more than one network, with a different ip address on each).  The look-up 
procedure is only going to return one name.

If you need alpha to have an ip address, give it a Class C address.  For 
extra robustness, put the network ip addresses (xxxx.xxxx.xxxx.0) for 
localdomain and computers.org in /etc/networks.

It's probably not a good idea to use a real top-level domain.  Why not 
knock off the org and just use alpha.computers ?
