When doing an AAAA lookup for mirror.centos.org, our BIND resolvers are throwing FORMERR errors. It appears this is because mirror.centos.org is a separate zone delegated to pdns1.centos.org and pdns3.centos.org, however when queried for a non-existent record it's returning the SOA for centos.org in the authority section of the response (instead of an SOA for mirror.centos.org as it should). Is there someone on this list who could update PowerDNS to serve the correct mirror.centos.org SOA record for that zone, rather than the centos.org SOA? [please copy me directly in any responses as I'm not subscribed to the list] Thanks, Tom Example: → dig @ns1.centos.org mirror.centos.org aaaa +norecurse ; <<>> DiG 9.8.3-P1 <<>> @ns1.centos.org mirror.centos.org aaaa +norecurse ; (1 server found) ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 56358 ;; flags: qr; QUERY: 1, ANSWER: 0, AUTHORITY: 2, ADDITIONAL: 2 ;; QUESTION SECTION: ;mirror.centos.org.
