- Mitigation guidance
- To mitigate the risk of this denial of service, configure BIND resolvers to restrict recursive queries to trusted clients only. This can be achieved by setting the `allow-recursion` option in the `named.conf` configuration file to specific IP addresses or networks. After modifying the configuration, the `named` service must be reloaded for the changes to take effect, which may temporarily interrupt DNS resolution.
