When these conditions are met, the DHCP server initiates a dynamic DNS update when assigning an address to a client.

When the DHCP server grants a lease to a client that is subject to DDNS updates, the server updates its database and e Directory to store the transaction.

We will start by copying the files so we have a backup remaining if anything goes wrong: 1.1 Copy the zone database files: We now need to add the key to the bind configuration and tell it what zones that we want it to allow updates on.

I’ve included the whole contents of my file here and marked the changes that I’ve made in bold.

But for my own home network I really think that the /dev/urandom will be sufficient.You must also specify a zone reference in the Subnet object so that the DHCP server can determine which zone to update.When DDNS is active, the DHCP server updates the DDNS server for the zone, adding or deleting the corresponding Address and Pointer records.What I think is more important is to always stop the bind service before making any changes to the database files, otherwise they might be overwritten by bind.

Examples of how to stop and start the bind service: The only way that I can think of to avoid this problem is to split your domains into two sub domains, for example lan. You could then have the DCHP server to only update the lan domain.The default profile suggests that these files should be put in /var/lib/bind.
