How to prevent in-addr.arpa queries from being forwarded to upstream DNS?

[aru]

I noticed that some devices are sending upstream in-addr.arpa queries, including certain IoT devices and AiMesh nodes. Since these queries consume my NextDNS query quota, I’d like to know if this behavior is considered normal. Also, is there a way to configure the system so that in-addr.arpa queries are resolved locally instead of being forwarded to the upstream DNS?

I blocked the .arpa top-level domain (TLD) in my NextDNS settings, which made these query issues more apparent.

You can add a line to /jffs/configs/dnsmasq.conf.add:

local=/168.192.in-addr.arpa/

Do you still have “Forward local domain queries to upstream DNS” disabled on the WAN page? It should be disabled.
