But what about:

     VerifyReverseMapping
             Specifies whether sshd should try to verify the remote host name
             and check that the resolved host name for the remote IP address
             maps back to the very same IP address.  The default is ``no''.

?

I usually configure my sshd with -u0 to prevent hostnames being truncated
in wtmp/lastlog, for better audit trail.
