IPv6 addresses for Exchange Points

At the RIPE 39 joint meeting it was clarified that we should cater for the 
support of both types of IPv6 exchanges, viz:

*	allocate addresses for IPv6 exchange infrastructure only (no onwards

allocation in the manner of a backbone ISP). 
*	allocate a sub TLA to the IPv6 exchange which will then act in the 
manner of an ISP and allocate downstream.

In order to progress this, I would like to propose: 

*	 IPv6 exchanges that need addresses for the purpose of internal
addressing 
can apply for the addresses already set aside for this purpose and held by
IANA, 
as per RFC2928 and RFC2450. In this case a /48 allocation will be
sufficient. 
(How IPv6 exchanges should apply for these addresses is out of scope - 
either direct to IANA, or IANA allocates down to RIRs first).

*	IPv6 exchanges that plan to onward allocate addresses in the manner
of an ISP 
should apply via the existing mechanism. The existing mechanism is currently
being 
reviewed and this review should take account of any changes necessary to
include 
IPv6 exchanges explicitly desiring addresses for onward allocation as being 
acceptable candidates for address space.

 Paul
