The `allow-update` block in `named.conf` enumerates the hosts/networks that are allowed to issue dynamic DNS updates. This is required in Active Directory and other environments where clients and/or DHCP servers create DNS records automatically. By default, the block is omitted from the generated configuration file. The `named_allow_update` variable can be set to a list of patterns (e.g. CIDR blocks, ACL names, etc.) to populate it. |
