Use FlooydDNS+ as a global nameserver to route DNS queries from all devices on your tailnet to NextDNS.
To add FlooydDNS+ as a global nameserver:
Open the DNS page of the admin console.
Go to Nameservers, then select NextDNS from the Add nameserver drop-down list.
Enter 2a07:a8c0::37:b96c and 2a07:a8c1::37:b96c for your NextDNS profile. This address is available in the Endpoints section of the setup tab of the NextDNS web console.
Click Save. The NextDNS profile will save as a global nameserver for your profile ID. One NextDNS IPv6 address will automatically add all IPv6 addresses for that profile.
Select Override local DNS to force devices to use NextDNS as a global nameserver instead of what is locally configured on each device.
