In the current pi.hole software, a reverse lookup of the IP of the pi.hole returns the name of the server: nslookup 192.168.169.6 6.169.168.192.in-addr.arpa name = raspberrypi.lan. But the beta shows: nslookup 192.168.169.6 ** server can't find 6.169.168.192.in-addr.arpa: NXDOMAIN Is this…

I just pushed an update to fix/pihole_ptr that skips replying with pi.hole if the request is for the loopback address. The reply will now have to come from /etc/hosts Does this now behave as expected?

Thanks for your report. I'll post an update here once we get the chance to investigate further and can work on a fix.

Please try if pihole checkout ftl fix/pihole_ptr resolves the issue for you. -- This is actually a tricky situation. What we did before v5.9 was replying with pi.hole only for the address defined in setupVars.conf (which may have been wrong). The new behavior is to reply with pi.hole for every …

With the fix version of pihole, I'm now seeing pi.hole for the raspi's ethernet interface, but now every machine on my lan shows pi.hole as its loopback interface name! My guess would be that the loopback interface should have an exception and just display "localhost". Interestingly, if I do "nslook…

[image] dmile: now every machine on my lan shows pi.hole as its loopback interface name This is interesting so this is sent to the Pi-hole regardless of that there is already a record in the client's local /etc/hosts (rendering an upstream query unnecessary) Which tool did you use for checki…

I tried nslookup on the pi-hole, on a separate Linux box, and Windows. I hadn't realized that a loopback address would be sent to the DNS server for resolution either.

[image] DL6ER: Should we reply with pi.hole for 127.0.0.1 and ::1 with pi.hole as well or should there be an exception for these addresses ? My vote would be localhost, since that is common to all installs. cat /etc/hosts 127.0.0.1 localhost ::1 localhost ip6-localhost ip6-loopback ff02::1 …

I believe that this mole has been properly whacked. I'm getting the expected responses to the pi-hole address and loopback addresses now.

Thanks for checking, we merged the change into the release branch. Please go back to the release branch to receive further updates: pihole checkout ftl release/v5.9
