Google is pushing it.  The problem is the brower vendors still don't
support multi-homed sites well despite it being in host requirements
for 20+ years.  IPv4 + IPv6 give you a multi-homed site.

If you have IPv6 connectivity then you can get to google over IPv6,
they will even return AAAA records if you register with them.  See
the browser problem above for why they are taking this route.
