~60%+ of internet traffic is mobile, which is ~100% behind CGNAT.
On desktop, only ~20% of US and European web traffic uses CGNAT, but in China that number is ~80%, in India ~70% and varies among African countries but is typically well over 70%, with it being essentially universal in some countries.
Overall, something a bit over 80% of all ipv4 traffic worldwide currently uses CGNAT. It's just distributed very unevenly, with US and European consumers enjoying high IP allocations for historical reasons, and the rest of the world making do with what they have.
