The only numbers I have ever seen published are Whereby's[0] they saw 17% used TURN.

There is a little more nuance then just paternalistic networks though. In same cases like NAT Mapping exhaustion you just can't give an individual user multiple long lived mappings. Address Dependendent filtering/mapping also makes sense in some cases. It makes P2P harder, but does give you the ability to provide your users more sessions at least!

We see about the same numbers Whereby does at Daily, globally across our whole user base. Bounces around a little but is usually just under 20%.

Way more for customers that are mostly serving corporate users, of course (firewalls). And more for mobile-heavy user populations.

Actually, that's a good reminder that it would be nice to understand the mobile data networks breakdown in more detail. Most of the US mobile data networks require TURN, as far as I remember when I last looked at this. But I don't know if that's true everywhere in the world.

That is awesome, thanks for sharing :) Lots of little details and they all effect each other. I really enjoy networking because of this.

I wonder if we come back to this in 10 years what this number will be. Linux on the desktop and IPv6 is just around the corner...

Thinking about it, v4 addresses and oil have a lot in common. The exhaustion/depletion is coming, but we keep finding ways to circumvent it. For oil you got fracking and sand. For v4 you see wider adoption of wide/carrier-grade NAT. In both cases it temporarily solves the supply problem really effectively. However it also ruins the environment.
