Problem is simple. DNSmadeeasy doesn't support DNSSEC. Route53 doesn't support IPV6. Constellix is expensive and not proven yet. Coudflare as DNS only, doesn't provide Automatic IP Failover. As you can see, almost every DNS provider is missing something. You can't add IPV6 support or DNSSEC by yourself... but... It seems quite simple to add Automatic IP Failover to Cloudflare's DNS. The question is. Is it worth it or is there another solution, provider, setting etc etc. Please share your opinion, experience, solution or anything you've got guys. The above is an example. I am open to everything.
