I'm trying to figure out my whole DNS situation now that I switched over to colocation. I have 2 servers, one hosts multiple sites and the other is just a backup.
I'm not sure what to do with DNS hosting. I could either host my DNS on both the servers (ns1,ns2 main server ns3,ns4 backup server). Does this mean if the main server goes down (ns1,ns2) it'll start using ns2,ns3? If so, can I just have ns2,ns3 point to my backup server IPs and traffic will just resume on the backup of the main server goes down?
If I go with a service like DNSMadeEasy.com, can I just point my main domain's name servers to ns1.dnsmadeeasy.com, ns2, ns3, etc.. and then point all my other domain's name servers back to my main domain OR would I have to point all my individual domains to dnsmadeeasy's name servers?
