DNS failover works by automatically updating a DNS record in case an outage is detected. For this feature to work you'll need to be using a DNS provider that we have integration for, we currently support Cloudflare & ClouDNS.

You'll first need to create a project, there you'll specify what hostname your application is using (e.g. app.nstoolbox.cloud). And you can provide an API token that we can use to modify the DNS record.

After that, you can specify "servers", these are IP addresses (either IPv4 or IPv6) that we will use, and to what uptime monitor it is linked. If a server is down, its DNS record is removed (in "Use all online" mode) or the next one is used in "Highest priority" mode.
