regarding cpanel dnsonly with multiple cpanel servers also multiple cpanel dnsonly servers

Hello, Now i have installed cpanel dnsonly on a new server, Also i've currently two cpanel servers with client's. I have many questions i need an answer for them. 1- Can i create multiple nameservers with more than once cpanel dnsonly? This means if i installed cpanel dnsonly on server1.com, server2.com server3.com as cpanel dnsonly servers is this should work? 2- When i connect the two cpanel servers with the cluster dns cpanelonly Do i have to link ( the two working cpanel servers with client's ) with each other through api or is it enough to connect the two cpanel servers inside the cluster server also add the cluster server to these servers through the api inside whm ? i hope you got what i mean. 3- Is this will make google pagespeed Reduce initial server response time? 4- Also we have issues with intodns.com which says the nameservers have different ip's ( I've set the new dnsonly server ip's inside the domain register but it says For dns1.website.com the parent reported: ['104..xx.xx.xx'> and your nameservers reported: ['64..xx.xx.xx'> For dns2.website.com the parent reported: ['104..xx.xx.xx'> and your nameservers reported: ['64..xx.xx.xx'> while the 104.xx.xx.xx it's the cluster ip and 64..xx.xx.xx is the cpanel server with client's so how to fix it ? As we have added the cluster cpanel dnsonly inside the domain register right but it says the nameservers still have the cpanel server ip where to edit these records? 5- I've set the cpanel servers inside the cluster as " standalone " which i marked the cpanel dnsonly inside the cpanel servers as sync is that right ? Please advise and tell me if i'm working right on this thing your help will be appreciated. Best Regards.
