3.1 Edit /etc/bind/local: # # Make sure to change the ddns update style to interim: ddns-update-style interim; ignore client-updates; # Overwrite client configured FQHNs ddns-domainname ""; ddns-rev-domainname ""; # option definitions common to all supported networks... subnet 192.168.0.0 netmask 255.255.255.0 The configuration files now contains our secret key. We also have to give the DHCP-server the permission to read and write it’s own file.
option domain-name "home.lan"; option domain-name-servers lan; default-lease-time 600; max-lease-time 7200; # If this DHCP server is the official DHCP server for the local # network, the authoritative directive should be uncommented. 5.1 Remove the general read rights from the configuration files: The dns database files are now being rewritten by the bind service.

ddns-updates on; ddns-update-style standard; update-conflict-detection false; allow client-updates; ddns-domainname "local.domain.com"; ddns-rev-domainname ""; update-static-leases true; default-lease-time 7200; max-lease-time 7200; authoritative; [...] Whenever a client gets a new IP from the DHCP, the DNS registration works perfectly.
For testing purpose, I had set the lease expiry to minimal time.
