I've long since decided to avoid using my ISP's dns and went to running PiHole with the upstream dns being 8.8.8.8 and 1.1.1.1 Tim. On Sun, Aug 24, 2025, 12:01 PM steve--- via WLUG <wlug@lists.wlug.org> wrote:
Hey all. I was wondering since were all? Worcester or surrounding and dealing with Spectrum as an ISP, if you’ve run into the same thing I have in the last few months.
I used to, as you’ll see soon, run unbound as a recursive DNS server in my home network to cache and limit external DNS queries that was the forwarder behind Pihole. It worked great for a very long time.
But a few months ago, my internet went down, and It turned out to be non cached dns queries starting to fail. I realized in logs that unbound was getting errors reaching out to dns servers and disabled it until I could investigate instead forwarding to cloud flare temporarily.
Now that I have had time to research and investigate, I have found that at least SOMETHING is intercepting my my queries to authoritative DNS servers when I reset unbound and it throw’s away the response because they aren’t “AA” status responses and it never caches the root dns and therefor won’t resolve anything.
I come to find out the “authoritative” servers are responding with a status of RA which means it’s not the actual authoritative service when I query manually, dig @198.41.0.4 . NS +norecurse an actual authoritative, and that this is most likely a change Spectrum has made. Has anybody else ran into this? Is it actually Spectrum. I guess I haven’t dug far enough yet to see if its may be a firmware update to my router, UDM PRO yet. Still working on that, but though I’d ask this group first before I dig into that and save myself the time and go straight to ISP workarounds.
Thanks in advance! Looking forward to our next meeting!!
