That means removing A records won't do any good.
If you give the DJBDNS name server multiple IPs for the same machine, it will return a set of 8 at random. Won't Windows (and hardphones??) then try those in order until they succeed? If the address they reach later becomes unavailable, will the be bright enough to try the other addresses? The hard phones must surely expire their DNS cache at some point?
