this. Now some remote machines will as for the name associated with the IP address of machines sending the remote machine a query, to try to see if someone is spoofing the IP address, but as far as I know ntpd does not do that. Takes too much time and would make the time responses really bad.
ntpd doesn't care about who is sending it a query, and, in any case reverse DNS lookups often provide bad results, which won't match the preferred forward lookup, in the real world.
