I want my three domain in following configuration 1. XYZ.com as Main Domain with custom nameservers (ns1.XYZ.com and ns2.XYZ.com) Currently Code: I have changes A records at godaddy to match my servers IP addresses hostname of server 1 is server1 A record server1 poining to master server IP address hostname os server 2 is server2 A record server2 pointing to slave server IP address server1.xyz.com and server2.xyz.com now lands at default apache page www.xyz.com gives DNS error. 2. ABC.com as reseller domian having nameserver of main domain to manage DNS records 3. ABC1.com as client domain to reseller domain ABC.com I have attached ISPConfig Report for both the servers I can share this report with proper IP Addresses and my domain names in case that helps.
