Hello Les,
Forgive me for this sidestep, but you are saying that Windows/IE
actually ignores bad IP addresses if a site lists multiple IP's in a
DNS lookup? I tried this approach for some redundancy a couple years
ago and it didn't seem to work as you suggest. If it has indeed
changed to work that way, this will help one of my clients immensely.
