ACL Control

Access Control (ACL) by IPv4 and IPv6 Prefix to Guarantee the Security of the Recursive DNS Service.

In BrbOS, you can create ACLs to ensure that only authorized network clients are served and that the recursive server can query external DNS servers, all directly from your DNS server.

With this, you can establish rules such as:

Accept requests only from specific ranges, such as 192.168.0.0/12, and allow queries from other ranges, such as 192.168.100.0/24 and 192.168.200.0/24;
Allow only recursive queries for RFC 1918, while responding to zone records for any IP, providing flexibility and security;
Configure the server to respond only to queries for specific zone records, without functioning as a recursive server;
Deny recursive prefix queries or zone queries by prefix, further protecting the integrity of your network against external threats.

With BrbOS Access Control (ACL), you have the power to customize the security of your DNS server according to the specific needs of your network, ensuring a safe and reliable online environment for your users.
