IPv6 for IXPs

wording quibbles:

s/assigned by upstream ISPs/acquired through other appropriate means/

could be that the ix operator could qualify for normally allocated space
all by themselves.

i suspect the 'most cases' is the /64, a single exchange mesh, and that the
multiple interconnected meshes, which whould need the /48, is a rare case.

the ix does not annouce mesh address.  isps on the mesh may.  so i would say

the rirs should warn the ixp that isps usually do not announce mesh space to
their peers, so that the ix space allocated under this policy is likely not
to be visible globally.
