兩個網域名稱的DNS問題

[b1206]

各位網友晚安︰
請問我有兩個網域名稱及兩個真實IP，例如︰
ns1.pigoo.com 210.243.201.240
ns1.psnet.com.tw 210.243.201.250
以上都是真實域名及真實IP，要如何在一部DNS主機設定？如果是一個域名一個IP這樣我會設定，所以我只好架了兩部主機，很笨吧！但只能先這樣交差。
我在網路上已經找了好久，但是都沒有相關範例，請問各位網友知不知道那裡有相關資料或是能幫我看看那裡出了問題？以下是我的設定檔。謝謝！

我用nslookup
server 210.243.201.240(dns.pigoo.com)可以解出dns.psnet.com.tw(210.243.201.250)。
但是用server 168.95.192.1卻解不出dns.psnet.com.tw。
如果我用server 210.243.201.250也解不出dns.psnet.com.tw。

反解部份先不管它，我想先解決正解部份。

謝謝各位。
