I've heard plenty of accounts from people (and these were techy people even, not just the ones who only go to Facebook and think that's the Internet) who lost v4 and didn't even realize for days, so I'm not sure how true that is... but more to the point, when we say an ISP is v6-only it usually implies some form of backwards compatibility method for reaching v4 hosts over the v6-only service. Commonly that's NAT64, which maps v4 into the v6 address space. The resulting service is v6-only (you only get a v6 address and have to talk v6 to the ISP) but you can reach v4 servers by talking to the v6 addresses to which they've been mapped. |
