Home network - possible to go IPv6-only? (sh.itjust.works)

Hi. This is my first post on Lemmy.

I want to test going IPv6-only in my home. I already enabled IPv6 functionality on my router. I can get two addresses from it on my computer: 192.168.0.x and 2402:xxxx (sorry, cannot remember the full address). My router shows two WAN IP: 100.64.x.x and 2402:xxxx.

If I disable IPv4 DHCP on my router, my computer shows only the IPv6 address, but many websites break. Is it not possible to go IPv6-only?

Sorry if I am not clear, I am not good in speaking English.

The only practical way to go IPv6 only right now is to use NAT64. This allows you to access IPv4 websites using your computers IPv6 address however it's not trivial to configure, you'll need a proper router(or Linux server), not just whatever router your ISP provides, and said router will still need an IPv4 WAN address but your PC, phone, etc can go IPv6 only and still access legacy sites like GitHub etc. For reference my home network is IPv6 only. I use jool for NAT64

I need to flash OpenWrt on my router?

Most likely, yes. (Are there any off-the-shelf home routers which support NAT64 out of the box??)

You need to be familiar with the command lines too, but that's almost a given since it's OpenWrt that we are talking about. Follow the tutorials here for activating NAT64 on an OpenWrt router.

Consumer routers, no, enterprise routers...yes
