Hello.
after many trial and errors ( mostly errors ) i decided reconfigure my vps and thus use free dns since i only have one ip address.
I registered a domain from godaddy. ( should have registered with centOs ). used centOs nameserver in godaddy.
in free dns manager , Created a zone file for my VPS host name . in Centos web panel , use centos name servers in Edit Name server ips. and two name server zone been created in my dns zone list.
now , if i create new user , this will automatically create zone file in my DNS server with proper info.
do i need to use free dns manager to create the zone for new Domain of the user ? or free dns manger for my vps only needs to have a record of my VPS host name ?
i hope i explained thing properly
