This surely is not possible.
Actually it depends what you mean by the network.  If you are connected to the internet, then the "network" consists of several million machines - you probably don't want that (and not possible anyway).

If you mean your local network, then you want to find the DNS used to identify your network machines - you may be able to connect to that using JNDI and do a simple search.

no CEHJ,

That returns the ip addresses of particular host

  say some thing like getAllByName("experts-exchange.com");

Do you really need all the adresses? you can send a packet to all the computers in a network by sending to the broadcast address. This is an special IP adress that means "everybody in a network".
If you really want all the POSSIBLE IPs in a network, you can deduce them from the IP of the interface, and the netmask, by appling a some bit-wise operations. If this is really what you want, tell me and I'll tell you the exact way.
And finally, if you want to know what computers in the network are up & running, you should use a network scanner, which what basically does is get all the possible IPs in a network as I mentioned earlier, and then try one by one to see which ones are up.
