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.
