Turn down the TTL. Let DNS caching take care of the rest... It doesn't work because, as far as I've seen, the clients (ok, netscape) doesn't ever requery the DNS. I'm not sure what state they're at now -- but they're moving towards doing all the resolver work themselves so as to get multithreaded behaviour. Maybe we can convince the browser writers to use ttl.
