I don't think this is right, you probably want 

  ddns-rev-domainname "in-addr.arpa.";

as the dhcp server reverses the ip address and adds ddns-rev-domainname.
So with your statement, and say the host was given an IP address of
192.168.3.50 you would get 50.3.168.192.3.168.192.in-addr.arpa. which
is not right.

Do you get any error messages on your DNS server, perhaps update denied
messages?
