Web Hosting DNS redundancy
Posted on 2010-09-23
I have a virtual private server with 2 IP addresses on it. I have my own nameservers using ns1.mydomain.com and ns2.mydomain.com but it is configured at the registrar - These point to the 2 IPs on my VPS.
Sometime ago, the registrar had an outage and I want to create some redundancy. So I have another registrar where I can create ns1.anotherdomain.com and ns2.anotherdomain.com and point them to the same 2 IPs on my VPS.
So I presume then I would just add these NS records to any customer domain so that they use the 4 nameserver records I have -
Is this the correct way to create some DNS redundancy.... Any advice much appreciated.
