Yeah, my first idea is that DNS is a lousy access-control mechanism.
Anybody can bypass it by using IP addresses in URLs or just running their
own DNS server.
Having said that, you could set up a special, private DNS with a wildcard A
record in its root zone. That would accomplish what you want for those who
_want_ to be spoofed.
