If you intend to have 1 server with just a few domains its probably not worth while. I use DNS cluster mainly because i have multiple servers and do plan to add more in the near future. This setup allows me to maintain only 2 name servers across all the servers so its also easier to manage domains and migrate them between nodes if 1 server is down or something like that.
Forgive my stupid questions, but I prefer to ask them so I can understand the logic.
That is. if we have DNS Cluster servers configured: ns1.mydnsserver.com - ip: 127.0.0.1 ns2.mydnsserver.com - ip: 127.0.0.1
Domain went down or was attacked for some reason or just expired (as funny as that sounds) and is being transferred to the second domain with NS records? And here comes the question, is it possible to display a message like:
Host - works (that is, my computer from which I try to visit H.com)
NS Server 1 - working
NS Server 2 - working H.com hosting is not working
My dns cluster setup as multiple machines with different IP addresses. Not sure why your example has same IP. Each dns server primary and secondary will store the same DNS Zones, the advantage of this is if 1 of the server goes down either 1 will still host the dns zones. This can be useful for receiving emails.
If 1 of the servers went offline for an extended period of time, i will pull a backup from the remote backup server and restore it on another server, because the setup uses the same āname serversā i dont have to update the ns at the domain. I should be able to get it up and running within hours if such a scenario happen.
I have a Master - 3x Slave setup using the API keys, working just fine.
However, when I try to switch to DNSSEC (using all the correct settings), the 3x slave server delete the entries as soon as they are received successfully from the master server. So the synching goes well, but then the records get deleted (not the domain names, those remain). Switching back to a normal 1x Master ā 3x Slaves all is working fine.
Just now I got the tip to create unique DNS Sync users instead - will try and update this post.
