Which is what ISP are doing with 464XLAT deployments. IPv6-mostly networking and IPv4-as-a-service are things that are happening in real world right now.

Yeah in Japan my ISP even lets me choose which IPv4 provider I want to use, as the fiber network is IPv6-native and IPv4 is "just another service" like IPTV.

Wow, that’s very cool! Do you know how that works? Do they just connect you to a NAT64 gateway of your choice?

IPv4 is provided using DS-Lite or MAP-E depending on the provider.

I'm using OpenWRT and paid for a static IP so I had to manually configure all the details for the MAP-E tunnel in OpenWRT myself, I think typically the routers sold to consumers pick up the configuration automatically somehow.

Which provider are you using? I'm curious about this since there are not many OpenWrt guides for getting connected in Japan. Is your config similar to this write-up? https://github.com/fakemanhk/openwrt-jp-ipoe

I didn't need to do any configuration for DS-Lite or MAP-E, as DHCPv6 with a configured prefix got IPv6 working, although DNS is still broken when turning off IPv4 entirely.

I'm using en hikari on Flets Cross (10 gigabit) with v6plus.

I set it up like 2 years ago but this was in my bookmarks: https://zenn.dev/ebi68k/articles/6df7cfec64c281

edit: looking this all up again to refresh my memory, it looks like with my static IP the provider switches from using their default MAP-E to using RFC2473 directly instead, the configuration matches "IPIP" in this guide https://qiita.com/kouhei-ioroi/items/cf0c6228c5c1faef415a

Woah, MAP-E allows static v4 (and presumably inbound connections)? That seems neat and much better than DS-Lite!

[kalleboo]

I'm re-learning this right now since I kind of just set it and forgot it 2 years ago but while my provider typically uses MAP-E it looks like when you use a static IP it switches to using RFC2473 (IPIP6) directly without the extra port mapping that MAP-E adds ontop
