I have added the CNAME record pihole.mydomain.net pointing to pi.hole to receive a localized IP response based on the interface origin. The record is correctly resolved by tools making basic DNS requests like ping: $ ping pihole.mydomain.net PING pi.hole (127.0.0.1) 56(84) bytes of data. 64 bytes …

Please upload a debug log and post just the token URL that is generated after the log is uploaded by running the following command from the Pi-hole host terminal: pihole -d or if you run your Pi-hole as a Docker container: docker exec -it <pihole-container-name-or-id> pihole -d where you substi…

Am not sure but I believe that 0.0.0.0 IP as a substitute for the own IP only applies for DHCP options. Its only mentioned in the DHCP section on the man page: $ man dnsmasq [..] -O, --dhcp-option=[tag:<tag>,[tag:<tag>,]][encap:<opt>,][vi-en‐ cap:<enterprise>,][vendor:[<vendor-cla…

For this you are correct. I mistook the 0.0.0.0 for its meaning in DHCP flags. This seems to be more closely related to the handling of the special record pi.hole by Pi-hole specific code: From /etc/pihole/dnsmasq.conf: [...] # Local domain for Pi-hole # This domain is purely local and should ne…

Aha I see: $ dig +short @localhost pihole.mydomain.net pi.hole. 0.0.0.0 $ dig +short @localhost pi.hole 127.0.0.1 EDIT: It did used to work via the API: [image] Scope of the v6 API includes DNS / CNAME CRUD? Beta 6.0 You're close: $ curl -s --request PUT l…

I was just about to answer this, you beat me by a minute. This is also logged as 0.0.0.0 $ sudo pihole tail 23:49:12: query[A] pihole.mydomain.net from ::1 23:49:12: config pihole.mydomain.net is <CNAME> 23:49:12: config pi.hole is 0.0.0.0

After deleting the one I created via shell: $ curl -s --request PUT localhost/api/config/dns/cnameRecords/pihole.mydomain.net,pi.hole | jq { "took": 0.011423826217651367 } $ dig +short @localhost pihole.mydomain.net pi.hole. 0.0.0.0 $ sudo pihole tail [..] 23:56:21: query[A] pihole.mydomain.net…

You confused me here with the API, I thought it was an API issue. But this is the same no matter how the record is added to pihole

The API is this one: http://pi.hole/api/docs/ Or HTTPS: https://pi.hole/api/docs/

CNAME records pointing to pi.hole return 0.0.0.0
