Using public NAT64 services

It is not that simple to run your own NAT64/DNS64 as we saw in the last posts. One disadvantage is, that it will only work inside your private LAN - I suggest, you didn't put the Jool service in the Internet.   That in mind, it is may the best way to use a public NAT64 service. The only thing you have to do is to put their DNS addresses into your device configuration and - of cause - have a global IPv6 address on your device.

IPv4-Internet services 2022 - the bad guys

If you go for IPv6 only today - as explained in the earlier post - you need NAT64, because a lot of the Internet content is IPv4 only 😭 But, if you enabled NAT64 for your v6-only network, you will - hopefully - not recognize the lack of IPv6. For browsers there is a very cool add-on IPvoo , which will show you, how you reached the website. In the case of NAT with the well-known-prefix 64:ff9b::/96 IPvoo shows " 4 ". Which is correct and wrong at the same time, but a good decision to have transperancy about NAT64. IPvoo is available for Chrome and Firefox.

Tune your NAT64

If you follow my last post, you have now NAT64 up and running. The downside of the solution is, that you have to disable manually IPv4 on your client and configure public DNS64 servers.   That is quite uncool, because, if you change the network the disabled IPv4 comes to a network without NAT64, so you will receive NAT64-prefixed AAAA-records, but those websites are not reachble for you, because no router does the NAT64 😕 Rollback client First, you can rollback all configurations (IPv4 disabled, DNS entries) to default. That means: enable IPv4 set DNS entries to automatic Enhance OpenWRT Because we don't want IPv4 in our IPv6-only network 😏We disable DHCPv4 on the LAN interface. From the General Setting tab switch over to the DHCP tab, General Setup. Enable Ignore Interface, because we don't need DHCP.   In the sub-tab IPv6 Settings enter these two Cloudflare - or any different - public DNS64 servers:   2606:4700:4700::64 2606:4700:4700::6400 (seems, that the last one is the
