The issue is not what address to give it, but how. You either have to allow the empeg to pick up it's own IP address (using DHCP on a small network configured to use this protocol) or tell the unit manually (which means you have to get to the command line of the empeg). Since at the moment it doesn't look as if you could do the latter, then the first is the best bet.

Do you know anyone with small network? If so, ask them if they have DHCP on the network (many do). Go over there and plug in your unit, and it should pick up an IP address from their network. This is a good starting point; you could then go home and set up your Mac to use the same address range, and plug them back to back. With the Mac now pretending to be on the network you have just used, you should then be able to start using JEmplode.

This would be a start. It's primitive, and you would later on want to go back and set it up to be something more useful, but you could at least download some music.
