I know this might be off topic but hopefully not too far off. I heard rumors that there are ISPs out there running IPv6 only networks where the clients can still get to the IPv4 world without the $30,000 plus dollar expense of buying a NAT64 appliance to service 4,000 plus customers.

Look into stateless transition mechanisms like LW4o6 or MAP. You can push a few 10s of Gbps through a relatively modest PC with these and the right software. Eventually somebody will hopefully add them to the relevant router software. Since they're stateless, most of the common "match and manipulate" type packet pusher ASICs can presumably do it. It's not much different than an IPv6-over-IPv4 tunnel or MPLS switching in that respect. -- Brandon Martin

1. For many networks where youtube, netflix, and fb dominate, most traffic will run ipv6 end to end. 2. For nat64, opensource dns64 and nat64 are available and mature https://www.jool.mx/en/index.html

Hi Art, Less ISPs than mobile carriers (e.g. T-Mobile) where the operator has substantial control over the subscriber's CPE and can require the presence of a CLAT client for 464XLAT. The key challenge (and key cost driver) with v6-only eyeball networks is the wealth of obsolete v4-only client software your customers use that might, if you're lucky, dribble away over the next few decades.
