This is fundamentally a bad thing. What happens when I take MY DNS server,
and tell it that
10.100.2.23 IN PTR foobar.my.domain.com
[acknowledging that 10.x is an RFC1918 address, but SOME valid address].
Your "security" will confirm that "YES, 10.100.2.23 is part of
.domain.com" and allow me access. Is that what you wanted? I highly doubt
it.
I think you probably want to be using IP addresses in your hosts file, and
not domains.
