Based on this passage in your draft:

   A possible problem of such addresses is that the shared addresses can
   not be used for global communication. So, it is suggested that the
   root name servers with the administratively scoped shared unicast
   addresses have additional globally unique unicast addresses, which
   may be used for global communication such as zone transfer.

We seem to agree that there should be two addresses, one shared and
one unique.  If you check section 1.2 of my draft, you'll see that I
proposed using the unique address for delivery of zones and
administrative tasks.  If the term "AS-internal" gave you the
impression I meant that address was not globally unique and routable,
the term should certainly be changed.  How does "Shared unicast" and
"Administrative" interfaces strike you as a set of terms to use for
further discussion?

Thanks for clearing that up.

Assuage your fears, Masataka, and be at peace.

Not true.  See section 1.5:

  The organization administering the mesh of servers sharing a unicast
  address must have an autonomous system number and speak BGP to its
  peers.  To those peers, the organization announces a route to the
  network containing the shared-unicast address of the root name
  server.

I believe I have a complete local archive, if you would like to point
me to previous message-ids.
