Hi there, I am in the process of writing a custom backend with PowerDNS 4.1.5 and I have a question on the expected response for SOA records.
As an example, when I dig a random subdomain at google.com I get the following result: root@linux:~$ dig SOA asd.dsa.www.www.google.com @ns1.google.com ; <<>> DiG 9.10.3-P4-Ubuntu <<>> SOA asd.dsa.www.www.google.com ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, id: 9217 ;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 1, ADDITIONAL: 1 ;; OPT PSEUDOSECTION: ; EDNS: version: 0, flags:; udp: 512 ;; QUESTION SECTION: ;asd.dsa.www.www.google.com. IN SOA ;; AUTHORITY SECTION: *google.com <http://google.com>. 59 IN SOA ns1.google.com <http://ns1.google.com>. dns-admin.google.com <http://dns-admin.google.com>. 235282735 900 900 1800 60* ;; Query time: 197 msec ;; SERVER: 216.239.32.10#53(216.239.32.10) ;; WHEN: Sat Feb 23 15:32:17 DST 2019 ;; MSG SIZE rcvd: 105 The result returns the root of the zone being google.com and not the random subdomain that I have queried. I have written my backend to return the root of the zone similar to above, however in my dig results, the SOA record is returning the queried record in full. See below: JSON request that my backend processes: {"method": "lookup", "parameters": {"local": "0.0.0.0", "qname": " sdfsdf.sdf.kjhkjh.domain.net.", "qtype": "SOA", "real-remote": "0.0.0.0/0", "remote": "0.0.0.0", "zone-id": -1}} JSON response that my backend returns: {"result":[{"qtype":"SOA","qname":"domain.net.","content":"dns1.domain.net. dnsadmin.domain.net. 2019021901 10 10 10 10","ttl":10}]} dig results for a zone within my custom backend: root@linux:~$ dig SOA @(ns IP address) sdfsdf.sdf.kjhkjh.domain.net. ; <<>> DiG 9.10.3-P4-Ubuntu <<>> SOA @ns1.domain.net sdfsdf.sdf.kjhkjh.cpjonestest.net. ; (1 server found) ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 984 ;; flags: qr aa rd; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 1 ;; WARNING: recursion requested but not available ;; OPT PSEUDOSECTION: ; EDNS: version: 0, flags:; udp: 1680 ;; QUESTION SECTION: ;sdfsdf.sdf.kjhkjh.domain.net.

Is this something that is expected and/or valid? Regards, Chris.
