Hi,
What setting does dnsmasq's filter private changes exactly ?
I thought it boguspriv, but even if i enable it i see it in the dnsmasq logs that it sends ptr requests to the upstream, and i can’t see what changes in the config at /etc/config/dhcp.
This is dnsmasq-full 2.91 btw.
I see queries like PTR? db._dns-sd._udp.0.1.168.192.in-addr.arpa. going upstream, despite bogus-priv being active since technically that isn’t an IP address being queried.
What do you see in your logs?
Edit: I was able to block them by adding the domain to the local parameter in dhcp.dnsmasq:
option local '/home.arpa/168.192.in-addr.arpa/'
I narrowed it down i think my issue stems from Tailscale bombarding the network with PTR requests, not sure how to filter these as they might be routable. I try your dnsmasq filter

Make empty 1.168.192.in-addr.arpa. zone, they will cache nxdomain and leave you alone.
