A DHCP lease is a temporary assignment of an IP address to a device on the network. When using DHCP to manage a pool of IP addresses, each client served on the network is only “renting” its IP address. Thus, IP addresses managed by a DHCP server are only assigned for a limited period of time.

How to set up DNS with Bind9 and DHCP?

Where is the RNDC key located in BIND9?

I included the RNDC key from bind, located at /etc/bind/rndc.key by default, and associated it with the appropriate zone for DDNS updates. This is what DHCP3-server uses to authenticate itself to BIND9 in order to make updates. (Recall that I earlier allowed updates with this key in the BIND9 configuration).

What are the permissions for bind in DHCP?

The file contents should be kept secret. The default permissions are correct, owner:group = bind:bind with permissions of 0640. These settings will not work with DHCP as the owner/group is wrong. If you change the permissions, each time bind is updated you will need to change them back again. It gets annoying, see comments the below.
