wondering, have people deployed IPv6-only residential

but we'd be more interested to hear about network
operators deploying either MAP or lightweight 4over6 (not
just trials though, but actual commercial services)<br>

<div>Softbank (Japan) launched an IPv4-over-IPv6 service in
August 2012. They use what looks to me to be an
IPv4-in-IPv6 tunnel, but could be just a particular case
of MAP-E with no portset. The service is up to 1G down /
1G up and they do encapsulation in hardware in a
proprietary CPE.</div>

I remember them deploying 6rd, but I could be wrong. <br>
