BIND9 dynamic updates allow remote servers to add, delete, or modify any entries in my zone file. How do I disable dynamic updates under BIND 9 (named) for any zone?
Dynamic updates can be risky, and disabling them is recommended. Another solution is to limit dynamic updates using ACLs and TSIG keys.
Linux / UNIX named Disable Dynamic Updates
Edit named.conf, run:
# vi named.conf
For each domain zone, set allow-update to none:
zone "cyberciti.com" IN { .... allow-update { none; }; ... }

The default mode for ‘allow-update’ is ‘none’ in Bind 9.
You should have no need to disable this in a per domain basis.
