Re: Interim Policy proposal for IPv6 Address Assignment Policy forInternet Exchange Points

[Dave Pratt <]

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.

Cheers
Dave
