My previous fibre provider in Ireland was Virgin, and as far as I could tell, it was fully IPV6. Every device in my network got a public address, and self hosting stuff from home as was easy as setting up an A record at my DNS host. No faffing around with port forwarding, proxying, nat bullshit or whatever. My memory is hazy, but there might have been some firewall stuff I had to do on the virgin supplied router.
