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

    Ah, I see — thank you so much for taking the time to analyze and explain this. I really appreciate it! :)

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

    You're right, .arpa isn’t only for private IPs, and it’s possible some of the lookups are generated by the router itself. I checked the NextDNS Logs, and there actually aren’t that many .arpa queries — most of them are old (around mid-September). No new ones have appeared recently. However...

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

    By default, DNS Director is enabled and the router is set to Router mode, so internal devices should theoretically be unable to bypass the router—but in practice, it seems they can. Since SDN and Guest Network Pro are not used, .arpa queries will not originate from SDN or Guest Network Pro...

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

    Yes, it is disabled on my WAN DNS Setting. As per your suggestion, I added local=/168.192.in-addr.arpa/ to /jffs/configs/dnsmasq.conf.add and restarted the service with service restart_dnsmasq. After monitoring for a day, I noticed that the query volume remained unchanged. if it’s possible...

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

    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...

    Difficulties maintaining 160 MHz channel bandwidth

    Thank you for your explanation. I have checked the router’s NVRAM parameters, and wl_bw_switch_160 is set to 2, indicating that TDCS is indeed enabled and has not been modified or disabled. Therefore, the current ability to maintain stable 160 MHz operation is likely not due to TDCS being turned...

    Difficulties maintaining 160 MHz channel bandwidth

    In previous firmware versions, even if the bandwidth was set to 20/40/80/160 MHz with DFS channels and auto channel selection enabled, devices could initially connect at 160 MHz. However, after about 5–10 minutes, radar interference would be detected, and the connection would automatically fall...

    AiMesh node clients frequently disconnecting

    The RT-BE88U (4x4, external antennas) has such strong coverage that it acts like a magnet, “holding onto” client devices. Even when a device moves right next to the RP-BE58 (2x2, internal antennas), it may not let go. In addition, the wireless backhaul cuts the available bandwidth in half...

    vnStat vnStat-on-Merlin v2.0.9 [2025-Aug-14] - Data Usage and Data Limit Monitoring using vnStat

    Thanks for developing vnStat! It’s been a very reliable and lightweight tool for long-term network traffic monitoring. Currently vnStat shows RX/TX/Total traffic, which is great for historical usage tracking. However, for users who want to understand whether their subscribed bandwidth is...

    Diversion Alternate blacklist editing & possible wildcards?

    Considering the limited resources of my router, I have been consistently using the default standard blocklist while periodically reviewing the Diversion Statistics Report. Whenever I notice domains with tens of thousands of hits related to ads or tracking, I add them to my blocklist...

    Unbound After upgrading to firmware version 3006 that Unbound's hit rate has decreased?

    Thank you for the information. The default configuration file that comes with the Unbound installation package is already quite comprehensive, having been fine-tuned by many knowledgeable and dedicated contributors. It also includes numerous optimizations specifically tailored for the ASUS...

    Unbound After upgrading to firmware version 3006 that Unbound's hit rate has decreased?

    Thank you for your detailed explanation. So it turns out the change to serve-expired-client-timeout is what affected the caching behavior — this information is truly essential. It really helped me understand the issue. Thanks again! 👍 As it turns out, this change in the newer version was...

    Scribe Scribe v3.2.3 [2025-Aug-24] - Entware syslog-ng and logrotate installer for Asuswrt-Merlin

    I really appreciate the Scribe and uiScribe tools—they make it easy to categorize and read system log information clearly. Not only can they collect system status from AiMesh nodes, but they also allow for flexible customization to return specific information of interest. A sincere thank you to...

    Unbound After upgrading to firmware version 3006 that Unbound's hit rate has decreased?

    Your observations are very likely correct. If the same issue can be reproduced across different platforms like pfSense, then it’s probably not related to the 3006 firmware. Instead, it may be an issue with the Unbound 1.23 core version itself. I also found a similar report from another user on...

    Unbound After upgrading to firmware version 3006 that Unbound's hit rate has decreased?

    Actually, I didn’t change the setting initially — it was 8M by default when I encountered the 40% hit rate issue. I suspected the low hit rate might be due to cache exhaustion, which is why I increased it to 16M. But even after increasing the cache size, there was no noticeable improvement...
