Geo addresses are just ordinary IPv6 addresses that
work the same as any other IPv6 addresses. They differ
from the current IPv6 addresses in only two ways. One
is that they come from a well-known prefix so that
anyone who chooses to can apply different policies
to these addresses. The other difference is that the
RIRs allocate these addresses according to a geographical
hierarchy and pass on the requirement to XPs to maintain
this geographical hierarchy.

This means that the allocation to an endpoint does not
come from their provider. It is provider independent.
Instead, the allocation comes from the local exchange
point operator. At this point, these addresses are
usable through any provider connected to the XP
and the routing announcements for these addresses
can be aggregated globally to a very small number
of entries in the so-called global routing table.

This doesn't prevent anyone from continuing to 
use provider allocated IPv6 addresses in the same
way that they are used in the v4 Internet.

The ITU can make credible arguments that the
existing random allocation of IPv4 addresses 
will not scale in IPv6 and therefore an alternative
is needed. If the Internet community does not
provide some type of geographic addressing that
as an alternative to the ITU's proposal, then
the ITU's position can easily win by default.
We can no longer ignore the phone network because
in the 21st century, the Internet *IS* the phone
network. I disagree with the ITU position.
