Fwd: ddns-updates off; within pool doesn't work

Hi, everyone!

I have a question about dynamic dns updates in dhcp.
I'm trying to exclude one pool of subnet from dynamic updates.

This is a part from my dhcpd.conf:

ddns-update-style interim;
ddns-updates on;
update-static-leases on;
allow-unknown clients;

subnet netmask {
  pool {
    deny unknown-clients;
    ddns-updates off;
    ignore client-updates;

  range dynamic-bootp;
  allow clients-updates;

But it doesn't work: dhcpd still updating dns within this address pool.
What I'm missing?


P.S.: Sorry if this is a duplicate message.
