add new Domain in SOA record use ns1.he.net ?

[JackYang]

I try add new domain.

I use dual stack mode in my network. so I add new domain, and delete ns1.he.net ( use ns2 ns3 ns4 ns5.he.net )

But I find my SOA --> example

xxx.com.tw.   86400   IN   SOA   ns1.he.net. hostmaster.he.net. (
               2014010718   ; Serial
               10800   ; Refresh
               1800   ; Retry
               604800   ; Expire
               86400 )   ; Minimum TTL

I think SOA ns1.he.net must be => ns2.he.net or ns3.he.net or ns4.he.net or ns5.he.net , but I can not changed it !!

This is some error or not ?! who can tell me ?!

Not an error.  See "hidden master."  The NS records govern where others will query for your domain.

Thanks for your response, I will continue to learn "hidden master &  Stealth (a.k.a. Split or DMZ) DNS Server".
