Two WAN IP's

[ithardware]

I don’t know how to word this, but here we go.
I have 2 sites and 2 webservers. if the main site webserver goes down and want the second webserver to take over. I have two external IP’s for the website already, so can I add those two IP’s in the DNS area and have it failover?
I tried it already, but it didn’t work for me, so I don’t know if I’m doing something wrong or that’s a limitation.

Thanks,

Rollover IP Feature in Cloudflare

If you have two A records and nothing else then clients will connect to any address, despite of its status. That’s how DNS works. With Load Balancer you can have multiple origins (or a single origin with multiple IP addresses on different providers for network redundancy) and it will monitor the status and follow the rules you set on how to proceed if one address is down.
