IF you mean missing availability of ipv6, I don't think that there are any pages you can't see on ipv4?

And there won't be while ISPs are lagging in their adoption, meaning nobody can set up a IPv6-only site if they expect to be accessible by everyone.

Also, there's more than sites: an IPv4-only client can't connecting directly (P2P) to other clients behind carrier-grade IPv4 NAT, which leads to more centralized systems (and which give an advantage to large companies over more independent developers and open source groups).

These ISPs are holding everyone back, hence the site submitted in this thread.

I know that NATs were not designed as security features, but I'm not sure if we want to have every device out there to have an IP address without NAT. I think that this would bear massive potential for botnets to take over older machines. And replacing NATs with firewalls would ultimately lead to the same problem with P2P.

It's unfortunate for people with more technical knowledge, but most people don't have that, and there is point protecting them from attacks (even if it's their fault that they didn't update).

Perhaps only test pages:
