I made this post 3 months ago: https://wetshav.ing/c/ipv6/p/47377/frontier-communications-ipv6-support
I finally got an IPv6 prefix from my ISP (Frontier). Unfortunately they are using /64, so as I'm learning how to handle IPv6 inside my home network I'm finding out that I can't use SLAAC for subnetting.
My next step is to learn about DHCPv6 and succumb to corporate greed. Out of principle, I used the chat function to ask for a /56 and you can imagine the conversation that ensued.
Other comments around the internet are hopeful that since Verizon bought Frontier, and Verizon knows how IPv6 works, there's hope that in the future everyone will get a /56.
