Hello, This question has been asked a few times before but there doesnt seem to be a clear answer?
i have the following scenario
We want to provide failover for our domain that serves a simple web page - not round robin or load balance the IPs rather a primary and secondary DNS address.
As in the user types www.bob.com
and this tries first IP 1 and if this fails try IP 2
Our DNS is hosted externally not internally.
What would be a solution? Setting a low TTL? a colleague mentioned using a virtual IP
not sure how this would be implemented and where?
