Implement Cloudflare DNS

Is it possible to implement CloudFlare’s DNS or similar in front of Kurento / CoTurn? Or in any case, is there a way to optimize the connection to the media server from multiple points in the world?
If I am not mistaken in the SDP we only find the IPs of Kurento and the Turn server and we do not find the domains, so I was asking myself this question.

I’ve found this: https://blog.cloudflare.com/announcing-our-real-time-communications-platform/
Can be helpful?
