If all of the names refer to the same IP address, the names all are pointing to the same place, and there is no way for your machine to figure out which name someone attempting to connect actually used. Once you have separate IPs for each, only allow the servers to respond to requests at the appropriate IPs. If the servers are not smart enough to handle that, you may need to run a simple firewall to divert attempts to connect to invalid ports of a given IP addr. IMHO, it's a lot of work and the payoff is a tiny bit of asthetic appeal. Is there any practical reason you want to do this? Wanna make people think you have more machines than you actually do? ;) -- Crist J.
