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.

Unfortunately until website owners starts being aware that IPv6 exists, you can only go IPv6-only if you have NAT64. Look at this:

From this screenshot I can see a couple instances (3 Hetzner IPs, one OVH, one DigitalOcean, one AWS and one from AS211772 (they also do have an IPv6 range announced)) that are IPv4-only. All of them could have IPv6 support but they only add the A record on their DNS records and call it a day. It is very annoying to see that.
