Some of us have researched the IPv6 address scanning quite a bit. Some

* scan6 tool (man scan6) of the IPv6 Toolkit:

* An IETF I-D:

* An article on the topic:

* A presentation on the topic:

* (The address stats were produced with the addr6 tool of the
aforementioned toolkit)

Clearly, there are two separate challenges to "scan the whole IPv6
Internet". One is the prefix part, which has been explored by Robert
Barnes, and the other is the Interface ID part (discussed/tackled in the
above references).

There's still work to be done in the area, though.
