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.

[Apologies for multiple postings. I suggest to keep the discussion on <lir-wg@ripe.net> as it is related to address allocation policies].

Dear colleagues,

At RIPE 39 last week in Bologna the issue of IPv6 address assignments to Internet Exchange Points was discussed (see also my mail from 24 April 2001 to these lists).

There was consensus to assign a /64 to an isolated Exchange Point. It was further suggested to assign the agreed standard assignment size to a site (currently a /48) to a group of inter-connected Exchange Points.

An Internet Exchange Point was defined as follows:

3 or more ASes and 3 or more separate entities attached to a LAN (the same infrastructure) for the purpose of peering and more are welcome to join.

The RIPE NCC proposes to proceed with assignments for Exchange Points under the above policy.

Kind Regards, Mirjam Kuehne RIPE NCC
