the DNS format converter is failing with an error.  this suggests the
wire format of the packet we're receiving is bogus.  if the client is
ISC dhclient, it may be client config related.  if it isn't, could you
send client details and a server-side pcap to dhcp-bugs@?

yes, the ddns configuration is the same.
