Here is the story. I have 5 VPS Servers: A, B, C, D, E. On Server A (www.a.com) I have 3 IPs: 126.96.36.199 188.8.131.52 184.108.40.206 I configured the named DNS and GoDaddy to use the following above IPs as Name Servers: 220.127.116.11 NS1.A.COM 18.104.22.168 NS2.A.COM HOW do I set this up so Server B (ip: 22.214.171.124) or Server C (ip: 126.96.36.199) to use NS1.A.COM and NS2.A.COM as Name Server and for the rest of the other VPS. What that means is that I want to have Server A serves as the Name Servers for the rest of the VPS. How do I achieve this? Please advise how to configure other VPS to use the name server of the Server A NS1.A.COM? Thanks much.
