Yes, these can be randomized, but you don't generally want to do this with servers. You also don't have to use the MAC-based addresses on the server either. You can generate a random address and use that for your service. Or you can regularly generate addresses on the server and update DNS so that the service has a new address every x hours or days. Or you could have the server not have any 'public' addresses, and whenever a new client wants to connect a new address is generated just for that client (with a TTL).
