alt Hacker NewsMultiple ISPs in my country have already deployed IPv6 with NAT64 support, and with CLAT support now available, I think IPv6-only networks will be the next step for most ISPs.

IPv6 mostly (RFC 8925) is a rather nice migration option.
Modern operating systems will gladly do CLAT, and old operating systems (or fussy users) can still get their IPv4 by just ignoring the new DHCPv4 option. But admins can finally stop keeping an IPv4 around for every potential client as most applications and users really don't care.
There is also MAP-T which basically does CGNAT with IPv6-only provider network. The local network gets IPv4, the router translates to IPv6 which goes to stateless IPv4 NAT proxy. The advantage is that the proxy is stateless unlike CGNAT. The downside is requires custom code on the router.
