Thanks for clarifying. I think that’s why every device in the database is shown as offline(“unknown”). The hosts in the database have fictional names or the mac address because of quick registration, so these devices are not reachable via FQDN. Any chance to deactivate the up/down check or assign a static IP address to the host that can be polled for this purpose?

Hi there,

We just installed a pihole in our laboratory network, where our FOG (1.5.7.1, CentOS7) also is placed. Surprisingly FOG leads the list with a huge amount of DNS queries. Approximately every five minutes FOG asks pihole for the ip addresses of the devices that are in the FOG database. Why is that?

Best regards
