There is no fault here. You are still getting the DNS name resovled.

The "UnKnown" is just it doesn't have a DNS name for your 10.10.10.2 DNS server. If you add a static entry into adguard that maps 10.10.10.2 to whatever hostname you want to appear, that error will go away.

There's no fault here, however.

I have tried this method, but it was useless.

I'm pretty sure that Windows uses the currently configured DNS server for the 10.10.10.2 reverse lookup.

Is 10.10.10.2 currently Window's configured DNS server?

[Poiig]

Yes

[tjharman]

Hmm yes, I guess AdguardHome doesn't support reverse DNS lookups configured on itself. It works for me, but that's becuase my upstream DNS server is doing the reverse mapping.

Regardless, I still don't consider this a bug. AdguardHome is designed to block ads, I don't think there's a valid use-case for needing to properly answer specific reverse DNS lookups, is there (aside from the fact it reports unknown in nslookup)

[Poiig]

Yes, I also don't think it's a bug. But as an optimization item, we hope to support it in the future. SmartDns seems to have this feature.
