Many ISPs, particular in EMEA, don't even hand out public IP addresses to their customers; cf. CGNAT [0]. End users, at home, will get RFC1918 or RFC6598 IPs from their provider. While they could still use a dynamic DNS service, the public IP that it sees will actually be a public IP address that is shared by many customers. --- [0]: https://en.wikipedia.org/wiki/Carrier-grade_NAT https://en.wikipedia.org/wiki/Carrier-grade_NAT
