Reverse DNS doesn't mean much, they can set it to anything; can you forward match them to any amazon domain?

It's forward confirming reverse DNS. I assumed that everyone does that by default.
What everyone does by default doesn't matter really here, it's that an IP owner/user can literally set the reverse to any arbitrary domain regardless if the actual domain has a record for that IP. What matters is both match, thats all I meant
