Hi, The results of the dig command against the old server includes the A record for the isilon.hpc. This must come from your isilon-dns.hpc server so your bind must be performing recursion to present that value back. The PDNS server is only an authoritative server. For recursion, we use pdns-recursor here and use the forward-zone feature to route Isilon lookups to the correct server. > This is result of DIG command on the old server. > > ; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.23.rc1.el6_5.1 <<>> @127.0.0.1 isilon.hpc > ; (1 server found) > ;; global options: +cmd > ;; Got answer: > ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 45472 > ;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 1, ADDITIONAL: 1 > > ;; QUESTION SECTION: > ;isilon.hpc.
