Slave DNS Server & Manager download version

[balen]

Hello,

I'm trying te new Slave DNS Server & Manager download version.
But I'm a bit confused...

How do I implement the plugin correctly:

Is it correct to install the plugin on both name servers and link in ns1 > API > ns2 and reverse ns2 > API > ns1 ?
and link all extra 3, 4... hosting servers with API tot the 1 ns Server?

CWP Server 1 and first nameserver: Here i installed the Manager Plugin
IP:111.111.111.111

CWP Server 2 and Second nameserver: and also here I installed the manager Plugin
IP:222.222.222.222

CWP Server 3 >
X.X.X.X

CWP Server 4
.....

Please give some advice or better methods if I'm wrong?

Kind Regards,
Balen
