True, assuming high TTLs on the records. Given his design, I was assuming he was using low TTLs.


Though the problem still exists where web browsers may resolve the IP once and retain that IP internally until the browser exits. The solution to this is to use the same IP on both machines, either via a method like you suggest, or a hardware load balancer, or an anycast solution.
