The default allows access only from RFC 1918 private IP addresses. Due to the aggressive nature of the internet these days, it is highly recommended to not open up the recursor for the entire internet. Questions from IP addresses not listed here are ignored and do not get an answer. https://docs.powerdns.com/recursor/settings.html#allow-from Imagine an ISP network with non RFC1918 IP adresses - they can't make use of PowerDNS recursor. As of now VyOS hat allow-from set to 0.0.0.0/0 and ::/0 which created an open resolver. If there is no allow-from statement a config-migrator will add the appropriate nodes to the configuration, resulting in: service { dns { forwarding { allow-from 0.0.0.0/0 allow-from ::/0 cache-size 0 ignore-hosts-file listen-address 192.0.2.1 } } }
