Hiya all,
Unfortunately, I must respond against the proposal as it stands with use of a /64 allocation.
Allocations of /64 for the peering LAN can be obtained already from a separate block (I forget the details - but I think from a US based ISP only block managed by David Huberman). I fail to see therefore what this proposal helps with.
This does not solve the problem as I see it, which is how to reliably, and independently of a particular ISP, multihome the infrastructure associated with the exchange point. From which range do the addresses for www.IXP.net or lg.IXP.net or term-serv.IXP.net come from ?
For this I propose globaly routable allocations be made, with a size of at least /48. The IXP can then decide whether to use part of that for the exchange LAN, or whether to get a separate /64.
The initial allocations will be made with a boundary of /48 to allow for a change to be made if the consensus in Prague is for /48 rather than /64. The address allocation is for infrastructure - so it is likely to filtered, and it will all come from a /35 to ease filter writing. For external facing services the address allocation comes from members/customers rather than this allocation. f
