I am in the middle of creating my design doc for DNS. My aim is to hide my primary NS from external world. And I am planning to use only secondary servers for query handling.
I have created XYZ.com zone and added two NS RRs which are secondary servers. I am forced to give my primary NS details when creating SOA record. Whether the primary NS RR, which we have given in the SOA RR will be safe for the internet (threats) or not?
One more added question. Whether I need to register my primary Name server in APNIC? Because, primary name server wont be published to the external world. Whether its really needed to register this in the APNIC?
