Seems like I, at sometime, got the idea that it was the router that dished back a unique IP based on clients MAC and so forth. However, it seems to me now that the router was only supposed to dish out the prefix, ie network id, and the client would take that prefix and generate a unique IP based on its MAC. Thanks again, Andy
