that doesn't sound like an ipv6 deployment at all. bummer.

I don't think you can provision ipv<anything> over 'volte' ... volte is
just: 'send voice over ip to handsets'. The LTE standard does speak
strongly about requiring ipv6 though, so probably any LTE deployment does
have ipv6 as a component.

perhaps you mean that?

and again:
  1) some of the examples you provided are not reachable in the PRC,
because of some PRC local decisions/actions
  2) all of the examples you cited (facebook, youtube, google, etc) are
ipv6 enabled for the rest of the world.
  3) some of these properties even provide content from inside the prc,
over ipv6

I am betting there are other, larger, problems with ipv6 deployment in the
PRC, related to things like: "Why can I not get to facebook.com?" while in
the PRC.

the rest of the world basically disagrees though? ipv6 deployment is moving
further and faster every day... except in the PRC, it seems?

maybe don't do the censorship part then?
