I presented today at the DNSOP WG about reverse DNS, and how it's used.
The context is that in IPv6, it is hard for ISPs to populate PTRs. So, is
it worth the effort? see draft-howard-isp-ip6rdns

Someone said, "SSH using PTRs for security is stupid" and there was
thunderous applause.  I'm following up on the DNSOP mailing list to
confirm, but there seems to be consensus that the default behavior of
rejecting an SSH connection because a PTR record is missing is stupid.

So, what would it take to change the default behavior from rdns = true to
rdns = false?

Thanks,
Lee
