I don't see why. Major consumer-grade French ISPs give IPv6 by default on FTTH installations and the router is configured accordingly (Orange, Free, SFR, Bouygues Telecom). Generally, you get a /64. Of course, when using IPv6 there is no NATting, each of your device has its own IPv6 address of the /64 range allocated to you.

And yet they are still not doing it properly: they are supposed to be giving at least /48 for businesses and /56 for customers: https://www.ripe.net/publications/docs/ripe-690 https://www.ripe.net/publications/docs/ripe-690

  Yep, I'm happy my ISP actually does proper prefix delegation and hands me a /56. I still often wonder if a /96 for a host and /64 for a network would have been a more reasonable allocation strategy though.

  Some of them give /56, but you have to ask for it (it's free).

The addressing is exactly why IPv6 isn’t something most ISPs want you to have in your house. Right now blocking a bunch of home servers is easy - just don’t give people addresses. With IPv6 you’ll need to thread that needle some other way or give people access to something that will actually test your advertised bandwidth commitments. Edit: instead of downvoting how about having a conversation? That’s the great thing about this place, lots of diverse perspectives.

  Home servers are already blocked by contract policy and firewalls. What difference does the IP make? You can filter on prefixes too so shutting off your entire IP block is easy.

    Sure, they have other tools, but I think most users will be less understanding. NAT seems like a reasonable technological limitation, and filtering for the sake of filtering won’t feel that way. Besides, why shouldn’t users be allowed to connect to machines on each other’s network without a central gatekeeper in the way?

      Why would users care? None of the blocking is due to technical issues, it's contractual. IPv6 wouldn't change anything except make it easier for both the ISP and for users who stay within the contract terms.
